DRR Single I/O Modbus

DRR is a flexible, powerful and yet compact PID controller targeting multi-zone applications.
Analogue input is free programmable for temperature sensors including PT100 and thermocouples, as well as for process signals in mA/Volt. Current transformer input ensures monitoring of current.
Two logic outputs are conceived for SSR control with heating/cooling PID and/or alarm purpose. One analogue output is also available for command or retransmission of process or setpoint.
Extensive software features include Soft-start and Open-Close logic for valves.
Serial communication relies either on ModbusRTU  protocols.

Application fields include plastic extrusion, injection molding, packaging, furnaces, dryers, textile machineries and generally multi-zone heat treatment systems.
