Application and short description
ZIEHL STW1000V2 current relays monitor standard signals from instrument transformers for compliance with
a limit value. Units can be wired in series (current) or in parallel (voltage) to monitor multiple limits.
Measurement inputs for 0/4-20 mA and 0-10 V, adjustable hysteresis and switching delays plus the selection
facility to choose between the normally closed current and normally opened current principle for the relay
make it a universal limit switch.
