4 Channel Indicator / Temperature Controller (RTD Input)

Product Code: PRO-R

Four channel RTD (Pt100) indicator/temperature controller, ideal for numerous industrial temperature applications.

One of the key features of the PRO-R controller is the ability to average the inputs across 2, 3 or 4 temperature channels, and use this averaged value for a display source or for setpoint activation.

The units are supplied with 4 relay contacts which can be configured as alarms or used for on/off control.

A retransmission output is available as an option which will allow a single channel (selectable) to be retransmitted. An RS232 or RS485 communication module can also be specified.
