The Raspberry Pi Compute Module Zero, a castellated module built around a quad-core Cortex-A53 processor, continues to find its way into industrial hardware. EDATEC's latest entry is the ED-IPC1200, a fanless data acquisition gateway that pairs the CM0 with industrial-grade digital I/O, serial interfaces, and optional cellular connectivity in a compact DIN-rail-mountable enclosure measuring 105 x 86 x 26 mm (4.1 x 3.4 x 1.0 inches).
What sets the ED-IPC1200 apart from EDATEC's earlier ED-IPC1100 is the addition of four optically isolated digital inputs and four digital outputs, both rated at 3.75kV isolation protection. Combined with two RS-485 ports and one RS-232 port via Phoenix terminal connectors, the gateway can interface directly with industrial sensors, switches, and relays for data acquisition and lightweight control tasks. Networking options include 10/100 Mbps Ethernet, optional Wi-Fi 4 with Bluetooth 5.0, and regional 4G LTE CAT-1 modules from Quectel covering China, Europe, and the US. The unit accepts 9 to 28V DC input with reverse-polarity protection and draws roughly 5W.
Under the hood, the CM0 provides a 1.0 GHz quad-core Cortex-A53 (BCM2710A1), 512 MB of LPDDR2 RAM, and either 8 GB or 16 GB of eMMC storage. EDATEC ships it with Raspberry Pi OS in both 32-bit and 64-bit flavors, plus drivers for the industrial interfaces. The documentation also highlights support for Node-RED, CODESYS, Python, and OpenCV, making it straightforward to build automation workflows or edge vision applications without leaving the Raspberry Pi software ecosystem. Within Node-RED, the community-maintained node-red-contrib-modbus package handles Modbus RTU and TCP over the RS-485 ports, covering the broad share of industrial sensors and PLCs that rely on the protocol. For IEC 61131-3 development, the CODESYS Control for Raspberry Pi SL runtime installs via the CODESYS Deploy Tool directly onto the device, enabling programming in ladder logic, structured text, or function block diagram and turning the ED-IPC1200 into a compact soft PLC.
EDATEC already has the ED-IPC1220 in the pipeline, which doubles the digital I/O count to eight inputs and eight outputs and adds analog current and voltage inputs. The ED-IPC1200 is available now through authorized distributors starting at around $150 (€138), with pricing reaching roughly $200 (€184) depending on connectivity options.
