Product Details

Modicon 110CPU61200 is a robust micro integrated plc controller and reliable analog i/o cpu belonging to the Modicon Micro 110 legacy series, also known as the brick-style compact brick plc for standalone skid and machine automation. This all-in-one controller integrates CPU core, built-in discrete I/O, native analog I/O, real-time clock, battery-backed memory and dual serial communication ports within a single DIN rail housing, programmed with LL984 ladder logic via ProWORX NXT or Modsoft software. It carries onboard 2K words of user program memory and 1820 words of data memory, retaining register values through power loss by backup battery. The unit includes discrete DC inputs, relay discrete outputs, 4 analog inputs and 2 analog outputs, supporting standard 4‑20 mA and ±10 V analog signals for transmitters and variable control devices. Dual serial ports support Modbus RTU master and slave, enabling connection to HMI, remote displays and other Modicon Micro nodes. It supports side-by-side expansion with matching Micro I/O bricks to add extra discrete and analog points when signal demand expands. Front LED indicators clearly show run, fault, communication and individual channel status for quick field diagnosis. As a discontinued legacy spare, this micro integrated plc controller serves as a drop-in replacement to restore full machine sequential and analog closed-loop control for ageing Modicon Micro automation installations.

Supported Functions

This micro integrated plc controller executes continuous cyclic scanning of onboard and expansion I/O. The analog i/o cpu supports timer, counter, arithmetic operation, floating-point calculation and PID closed-loop regulation for pressure, flow, temperature and level control. This compact brick plc can act as Modbus master or slave to exchange real-time analog and discrete data with operator panels and supervisory systems. It supports alarm logging, recipe storage and time-scheduled sequence operation by its real-time clock. It runs comprehensive self-diagnostics to detect memory failure, communication timeout, analog over-range, I/O short circuit and low backup battery. When critical faults are triggered, it locks outputs to predefined safe states to protect field actuators and process equipment. Additional expansion bricks can be fitted to scale up I/O capacity for medium batch process requirements.

Core Functions

As a dedicated analog i/o cpu, this micro integrated plc controller directly reads switch, sensor and transmitter signals, executes user control logic, drives solenoids, contactors and modulating analog valves. Its native analog channels eliminate the need for separate analog modules for small process skids, while the Modbus serial ports build communication links for local supervision. This compact brick plc works as a direct spare to rebuild stable mixed discrete and analog automatic control for ageing Modicon Micro automation systems.
