Seneca Z-PID, PID Analogue Controller ModBus

Please note this product has been superseded by the Z-DAQ-PID

Description:

The Z-PID is designed to interface transducers and instruments with different analogue signals to a ModBUS RTU System with RS485.
The Z-PID also has an Analogue output and an integrated PID controller.
When the device is used in a temperature related application it's integratred PID controller can take into consideration the actual temperature and the desired temperature automatically adjusting it's output signal to ensure minimum under/overshoot.
