The TDMB422 is a dual-function time delay relay offering delay-on-make and delay-on-break operations in an 8-pin octal plug-in package. It features SPDT output contacts rated for 10A resistive load at 120/240VAC and 28VDC, with a 1/3 hp rating at 230VAC. Timing ranges are 1 to 1023 seconds in 1-second increments for both delays, set via DIP switches with ±2% accuracy. The unit operates on 120VAC input with ±20% tolerance, consumes ≤2VA, and includes green and red LED indicators for status. It mounts on 35mm DIN rail or surface with two #6 screws, measures 81.3 mm high, 60.7 mm wide, and 45.2 mm deep, and operates from -20°C to 60°C. Isolation voltage is ≥1500V RMS, and reset time is ≤150ms.
The TDMB combines both delay-on-make and delay-on-break functions into one plug-in package. Selection of the time period is accomplished with dual switches, one for the on delay and the other for the off delay. SPDT or DPDT output options provide isolated, 10A switching capability.
