Description

Electronic plug-in railway monitoring relay for battery voltages. The relay reacts on the mean value of a DC-voltage with ripple. The pull-in voltage and hysteresis (the difference between pull-in voltage and drop-out voltage) are adjustable by means of multiturn trim potentiometers.

The pull-in time after crossing the setpoint is < 15ms. The drop-out time is approximately 20 ms, which can be extended to 250 ms. Optional the relay can be supplied with fixed (sealed) set values, or led indication. The ACD relays are pluggable into standard D-U200 relay sockets.
