Product Details

140CPU31110 is mid‑range Unity processor for Schneider Modicon Quantum automation platform,compatible with Unity Pro programming software,designed for medium‑size industrial automation and process control applications.

It runs at 66MHz clock frequency with 548kB internal RAM,supports PCMCIA memory card for program storage expansion. This CPU is equipped with front‑panel LCD display for local status checking and fault diagnosis,multiple task mechanism supports cyclic main task,fast periodic task and multi‑group interrupt tasks.

Integrated native Modbus Plus and dual Modbus serial ports,realizes peer‑to‑peer interconnection between controllers,connects HMI,inverters and field instruments. It allows up to 2 optional communication modules to expand network functions,without native Ethernet port.

Support 2 local racks and maximum 31 remote I/O stations,realizes large‑scale distributed I/O deployment. Widely applied in water treatment,equipment manufacturing and power auxiliary control,used as replacement spare‑part for existing Quantum PLC systems.
