Popis
Plug-in electronic voltage monitoring relay with four change-over contacts. When the relay is activated there is a delay on pull-in. The delay time is adjustable with a lockable knob. The relay can also be supplied with a fixed time delay (no knob). The pull-in voltage is adjustable with a lockable knob. The relay can also be supplied with a fixed pull-in voltage (no knob). The relay reacts on the mean value of a DC voltage with ripple. The drop-out voltage level is fixed.
Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life. The ACTD4-U200 does not need an auxiliary supply.
The construction of the relay and choice of materials makes the ACTD4-U200 relay suitable to withstand low and high temperatures, shock & vibrating and dry to humid environments. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.
Application
These relay series are designed for demanding train borne applications. The ACTD4-U200 is used in applications for voltage monitoring with time delay.
