Love Series SCD

Series SCD DIN Rail Temperature/Process Controller

Series SCDUniversal Inputs, Up to 8 PID Loops, Modbus® Communications

The Love Series SCD DIN Rail Mount Temperature/Process Controller offers multiple PID loops in a compact size. Each SCD-1000 master controller can be combined with up to seven SCD-2000 slave controllers without any wires. Each controller has one universal input, one relay output and one user selected output. The outputs can be used for a dual loop to control heating and cooling or a single loop with an alarm. These controllers support up to 64 ramp/soak actions. The SCD series controllers are programmed via a user-friendly software program via the RS-485 Modbus® communications.
