Fanless Industrial PC for Space-Constrained Automation Cabinets | MPC-2018L
When an automation cabinet is already crowded, the computer must fit the drawing as carefully as the PLC, drives and terminal blocks. MPC-2018L is a strong candidate to evaluate because it combines a compact enclosure with useful serial, USB, video and network I/O. MPC-2018L uses an Intel Core i5-4200U processor with up to 8 GB DDR3L memory, while its fanless all-aluminum alloy construction gives the cabinet designer a clear mechanical starting point.
The I/O layout matters just as much as processor choice. MPC-2018L provides four USB 3.0 ports, two USB 2.0 ports, two RS232/RS485 ports, four RS232 ports, VGA, HDMI, and dual Intel I211 Gigabit LAN. That combination supports a serious cabinet-fit review without assuming a specific PLC, protocol or application result.
Why Cabinet Space Should Drive the Industrial PC Choice
A retrofit cabinet often has depth limits, existing cable routes and a service door that must still close. Start with the computer envelope, connector direction and removal path rather than selecting by CPU name alone. The 243 × 144 × 66 mm chassis with desktop or wall mounting gives the team a concrete envelope to place on the cabinet drawing.
Fanless all-aluminum alloy construction removes a fan from the component layout, but it does not remove thermal planning. Review heat paths, nearby devices, ambient conditions and technician access before fixing the final position.
MPC-2018L Configuration at a Glance
| Cabinet decision | MPC-2018L detail | Confirm in the project |
|---|---|---|
| Compute | Intel Core i5-4200U, up to 8 GB DDR3L | Workload and software image |
| I/O | Four USB 3.0, two USB 2.0, two RS232/RS485, four RS232, VGA, HDMI, dual Intel I211 Gigabit LAN | Device map, protocols and cable paths |
| Storage | mSATA and 2.5-inch SATA support | Capacity, write pattern and replacement plan |
| Expansion | One full-size and one half-size Mini-PCIe slot | Module and regional requirements |
| Power | 9–30 V DC input | Supply, protection and grounding |
| Mechanical | 243 × 144 × 66 mm; desktop or wall mounting | Clearance, bracket and service removal |
Use the Port Map to Prevent Cabinet Redesign
The four RS232 ports and two RS232/RS485 ports create room to map legacy instruments, drives, meters or service devices before the cabinet is frozen. USB 3.0 and USB 2.0 provide additional paths for local peripherals, while dual Gigabit LAN lets the integrator evaluate separate machine and plant-side traffic roles. These are physical options, not proof of a particular protocol or network architecture.
Send the supplier a device table with interface, connector, cable length, isolation requirement and software assumption. If the required serial mix or connector orientation changes, ask for a customised configuration discussion instead of redesigning around an unverified assumption.
Storage, Expansion and Service Access Belong in the Same Review
mSATA and 2.5-inch SATA storage support lets the buyer compare a compact system drive with a replaceable local-data path. Decide what belongs on the computer—application image, logs, recovery files or temporary data—and reserve access for the intended service action. The one full-size and one half-size Mini-PCIe slot can be evaluated for project-specific expansion, subject to module and software confirmation.
MPC-2018L's Windows 7, Windows 8, and Linux operating-system support should be checked against the exact image, drivers and lifecycle requirement for the project.
Power and Mounting Make the Drawing Actionable
The 9–30 V DC input gives the cabinet team a defined electrical condition to place beside the DC distribution plan. Confirm startup behavior, protection, grounding and isolation with the complete system. Desktop or wall mounting may suit different cabinet positions; check support, orientation, rear clearance and cable bend space before ordering.

Frequently Asked Questions
Is MPC-2018L suitable for a space-constrained automation cabinet?
It is a strong candidate when the 243 × 144 × 66 mm envelope, fanless construction, I/O, mounting and 9–30 V DC input fit the cabinet plan.
How many serial ports does MPC-2018L provide?
It provides two RS232/RS485 ports and four RS232 ports. Device protocol, isolation and driver fit still need confirmation.
What storage options are available?
mSATA and 2.5-inch SATA storage support are documented. Capacity and replacement access should be included in the RFQ.
Can the mounting or I/O arrangement change?
Univitech can review changed I/O, enclosure, mounting, power or software requirements through a customised configuration discussion.
