The TDMB4 is a multifunction relay with electronic time delay, consisting of 3 change-over contacts and 1 normally closed contact, for reliable switching of very low currents (1 mA @5 VDC) up to 10 A @ 110 VDC. A single TDMB4 offers 10 user-programmable timer functions. The switching time ranges from 0.1 second to 99 hours, adjustable via four 10-position rotary switches on top of the relay. Two LEDs indicate power supply and coil energization. The built-in magnetic arc blow-out ensures long contact life, while integrated contact separation prevents cross-pollution.
