EPC-102B Four-LAN Modular Industrial Box PC with Intelligent Thermal Control
4× Intel I210 LAN · BlockCore® function cards · intelligent thermal control · 337 × 160 × 47.5 mm · 2 kg · Fanless passive + fan assist under load
Four isolated Gigabit segments and a thermal design that knows when to ask for help. The EPC-102B carries 4× Intel I210 LAN so the production network, a management network, a camera subnet and an uplink can all stay separate without another switch. Its ports are not fixed either: serial, fieldbus and digital I/O arrive as BlockCore® function cards, so one platform covers CNC control, automation and gateway duty. Cooling is passive and fanless in normal operation, with automatic fan assist when load and ambient temperature ask for it — in a 337 × 160 × 47.5 mm, 2 kg aluminium chassis.

Why four isolated networks and a modular I/O layer pay off

Four LAN ports, because the networks are supposed to stay apart
One Ethernet port means everything shares a segment: the machine traffic, the camera streams, the plant network and whatever links the site to the outside world. The EPC-102B provides four Intel® I210 Gigabit ports, so a production network, a management network, a camera or vision subnet and an uplink can each keep their own address range and their own rules. That is the requirement behind industrial edge gateways and machine-vision controllers, and it is why the box is used instead of adding a second switch inside a cabinet that has no space for one.
- 4× Intel I210 Gigabit LAN, 10/100/1000M
- Production, management, camera and uplink segments kept separate
- No extra managed switch in the cabinet
- Intel NICs — predictable teaming, VLAN and jumbo-frame behaviour
- Mini PCIe socket left free for 4G or Wi-Fi
Fanless until the load asks for more
The EPC-102B runs passively fanless in normal operation: no noise, no filter, and no air path pulling cabinet dust, metal filings or oil mist across the boards. When the processor load or the ambient temperature approaches the thermal threshold, the intelligent thermal control system brings in fan assist automatically, and the fan itself is hot-swappable — a field replacement rather than a return-to-factory. You get the dust resistance and the silence of a fanless box, without throttling on the days the machine works hardest.
- Fanless passive in normal operation — no filter, no daily dust path
- Automatic fan assist when load or ambient temperature rises
- Hot-swappable fan: field replacement, no factory return
- Intelligent control — the fan runs only when it earns its keep
- Extended range −40–70 ℃ available for cold stores and outdoor cabinets


The I/O is modular, so one platform covers several machines
The EPC-102B is built on CESIPC’s BlockCore® modular architecture: serial ports (RS232, RS422, RS485), digital I/O and CAN bus are added with function cards rather than ordered as a different chassis. A CNC controller that needs three serial links, a gateway that needs CAN, and a panel that needs digital I/O can all be the same base unit with different cards — which simplifies spares, documentation and training across a plant. Three 12th Gen builds are orderable: i3-1215U, i5-1235U (part number C10.01.04.006) and i7-1255U (C10.01.04.008).
- BlockCore® function cards: RS232 / RS422 / RS485, DIO, CAN bus
- Add or remove ports without changing the base chassis
- Standard build C10.01.04.006 (i5-1235U, 16GB) and C10.01.04.008 (i7, 32GB)
- 9–36V DC wide-range input on a 3-pin terminal block, AT / ATX boot
- CE / FCC / BIS to EN 55032 & EN 55035, ODM / OEM BIOS and branding

FAQ
EPC-102B frequently asked questions
Questions about the four isolated LAN ports, how the intelligent thermal control and fan assist work together, adding serial or fieldbus ports with BlockCore® function cards, the 9–36V DC input and the mechanical fit.
What is the EPC-102B used for?
CNC machine control, factory automation, edge computing, energy management systems, multi-network routing and intelligent transportation. The common thread is the four independent Intel I210 Gigabit LAN ports: any installation that has to reach several isolated networks at once — an industrial IoT gateway, a machine-vision controller, a cell that separates camera traffic from production traffic — is where this model belongs.
Why does it have four Gigabit LAN ports?
So the networks do not have to be merged. With four Intel® I210 ports the box connects simultaneously to a production network, a management network, a camera or vision network and an internet uplink, each with its own address range and its own firewall rules, and without adding network switches inside the cabinet. That isolation is a hard requirement in industrial edge gateways, machine-vision controllers and factory automation systems that keep control traffic away from everything else.
How do the fanless design and the fan assist work together?
They are two stages of one thermal design. Under normal operating conditions the {model} is passively fanless — no noise, no dust drawn across the boards, longer component life. When the system detects high processor load or an ambient temperature approaching the thermal threshold, the intelligent thermal control system activates fan assist automatically. The fan is hot-swappable, so it can be replaced in the field. The result is the reliability of a fanless box with the headroom to survive peak workloads.
Can I add serial ports or fieldbus interfaces later?
Yes — that is the point of the BlockCore® modular architecture. Serial (RS232, RS422, RS485), digital I/O, CAN bus and other interfaces are added as function cards without modifying the base chassis. The same unit can therefore be configured for CNC, automation or process control duty, and a card can be added or swapped during commissioning rather than ordering a different model.
What power supply does it need?
A 1× 3-pin pluggable terminal block accepting 9–36V DC wide range, so the box runs from a standard 12V or 24V industrial DC rail without a separate converter. Boot mode is selectable between AT (auto power-on) and ATX (soft power); on unattended systems AT is normally chosen so the box comes back by itself after an interruption.
What processor builds are orderable, and what are the part numbers?
Three on the Intel® Core™ 12th Gen platform: i3-1215U at 1.2–4.4 GHz with 8GB, i5-1235U with 16GB — part number C10.01.04.006 — and i7-1255U with 32GB and a 512GB SSD, part number C10.01.04.008. The chassis, the four LAN ports, the thermal design and the BlockCore® card slots are identical across all three; memory runs to 32GB DDR5 on the 12th Gen builds.
What operating temperature range does it hold?
The standard configuration operates from 0 ℃ to 50 ℃, with an extended option to −40 ℃ to 70 ℃ covering outdoor enclosures, cold stores and high-temperature industrial areas. Storage is −10–60 ℃ and humidity 10%–90% non-condensing. Because the everyday cooling path is passive, the extended range applies without changing the enclosure or adding a filter.
What are the physical dimensions and how is it mounted?
337 × 160 × 47.5 mm and 2 kg, milled from high-strength aluminium alloy. It mounts on a wall bracket or a VESA plate, and the 47.5 mm depth keeps it inside standard cabinet and machine-frame clearances. Video output is a single HDMI, audio is provided, and the four USB 3.0 ports sit on the chassis for keyboards, service storage and peripherals.
What networking, wireless and certifications does it carry?
Wired networking is 4× Intel I210 Gigabit LAN; wireless options are 4G full network compatibility and Wi-Fi / Bluetooth, with a Mini PCIe socket available for a module. Certifications are CE, FCC and BIS according to EN 55032 and EN 55035, and the ODM / OEM service covers BIOS customization, boot-on-LOGO and OEM branding from the factory.
