Old Id.Nr.: 141648
Wiring diagram
Product description
The PID differential temperature controller with two 3-digit LED seven segment displays, 4 keys
and 3 relays is variably applicable due to its freely programmable general functions. The relay
contact K1 directly affects the main setpoint, formed by reference variable and the given offset
temperature. Contact K2 affects the secondary setpoint which is formed by the main setpoint via
overlap or which alternatively can be freely defined. Contact K3 affects adjustable limit values.
Sensor: Pt100
Range: -99...750
