Voltage Monitoring Type SW
DC Limit Relay for Standard Signals
DC 0/4 - 20 mA, 0/2 - 10 V
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 hyste-
resis and switching delays plus
the selection facility to choose
between the normally closed cur-
rent and normally opened current
principle for the relay make it a
universal limit switch.
Measurement inputs 0-20 mA
/ 0-10 V, switchable to 4-20
mA / 2-10 V
Limit adjustable 0-100 %
Hysteresis adjustable 5-30
%
On-delay adjustable 0.1...
