The TDMB622 is a dual-function time delay relay with delay-on-make and delay-on-break capabilities, offering an SPDT output with 10A resistive switching capacity at 120/240VAC and 28VDC. It operates from 230VAC input with delay ranges of 1 to 1023 seconds in 1-second increments for both functions. The unit mounts as an 8-pin octal plug-in on 35mm DIN rail or via surface mounting with two #6 screws, using PSC8 hold-down clips. Input voltage tolerance is -20% to 10%, with delay accuracy of ±2% or 50ms, whichever is greater. It features LED indicators for initiate and output status, reverse polarity protection, 1500V RMS input-to-output isolation, and operates from -20°C to 60°C. Dimensions are 81.3 mm H × 60.7 mm W × 45.2 mm D, weighing approximately 170 g.
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.
