Temperature monitoring relays STEP800R
Temperature monitoring relays with 4 (STEP840R) or 6 channels (STEP860R).
Each channel has associated with it:
-1 adjustable temperature trip setpoint
-1 output relay associated with this setpoint
-1 continuous temperature measurement, viewable on the digital display

These relays are designed for connection to Pt100-type platinum resistance temperature probes (not supplied) and are useful for monitoring the bearing and winding temperatures of large rotating machines.
