Plug-in electronic railway voltage monitoring relay with four change-over contacts for reliable switching of very low currents (1 mA @ 5 VDC) up to 10 A @ 110 VDC. It offers optional delay on pull-in and/or drop-out, with adjustable or fixed delay times. 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. The built-in magnetic arc blow-out ensures long contact life, with integrated contact separation, serial/data matrix traceability and an integrated snap-lock for the MTDV4-U200N.
