The AMiT AMR-CP4x series is a compact, DIN rail-mounted PLC engineered to function as a versatile communication hub and a fully programmable control system. Designed for seamless integration into building and industrial automation, this controller is defined by its rich suite of onboard interfaces. A key characteristic is the dual Ethernet ports with integrated switch functionality, which, alongside the RS232 and galvanically isolated RS485 serial ports, provide robust and flexible connectivity options for modern industrial networks. The unit is powered by a 24 V DC supply and housed in an IP30-rated enclosure measuring 106 × 99 × 62 mm, suitable for installation on standard 35 mm DIN rails.

What truly sets the AMR-CP4x apart is its ability to operate both as a standalone, full-fledged control system and as a centralized controller for remote I/O applications. It is designed with a "no onboard I/O" philosophy, instead relying on its exceptional communication capabilities to manage distributed field devices. This is facilitated by its support for standard industrial protocols including Modbus RTU/TCP and AMiT's own high-performance DB-Net/IP. For applications requiring wireless connectivity, the controller offers optional integration with AMiT's Poseidon 868 MHz wireless system and built-in GSM modem support, making it an ideal choice for remote monitoring, data acquisition, and telemetry applications.

The AMR-CP4x is more than just a PLC; it's an intelligent IIoT-ready edge device. An embedded web server empowers users to create custom web-based presentations for remote monitoring and control of process variables. Critical operational data can be stored directly onto a microSD card, enabling long-term data logging and offline trend analysis without the need for a constantly connected PC or external database. These features position the AMR-CP4x as a powerful, yet cost-effective, solution for OEMs and system integrators looking to build smart, connected equipment for building management systems, HVAC control, and distributed industrial processes.
