Plug-in electronic voltage monitoring relay with optional delay-on and delay-off timer function and four change-over contacts. The delay time is adjustable via a lockable knob (one delay adjustable, the other fixed) or fixed. The pull-in (Uon) and drop-out (Uoff) voltages are adjustable via internal screws or fixed, suitable for DC voltage monitoring with very small hysteresis. An LED indicates contact status and time delay, with a delay-off function for voltage drops up to 50% of minimum pull-in voltage and no auxiliary supply needed. Standard with magnetic arc blow-out; rugged construction with integrated snap-lock for the MTDV4-U200.
