Time Delay Relays Delay-on-Make TDU / TDUH / TDUL SERIES Encapsulated Solid-State, Delay-on-Make Timers Description The TDU Series are encapsulated solid-state, delay-on-make timers that combine digital timing circuitry with universal voltage operation. The TDU offers DIP switch adjustment allowing accurate selection of the time delay over the full time delay range. This series is an excellent choice for process control systems and OEM equipment. Operation (Delay-on-Make) Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output energizes and remains energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output. Features & Benefits Wiring Diagram L1 N/L2 Load may be connected to terminal 3 or 1. FEATURES BENEFITS Universal input voltage Meets wide application needs Microcontroller based Repeat Accuracy +/- 0.5% or 20ms, whichever is greater Totally solid state and encapsulated No moving parts to arc and wear out over time, and encapsulated to protect against shock, vibration, and humidity 3 time ranges available (0.1s to 2.8h) Makes it versatile for use in many applications DIP switch adjustment Provides first time setting accuracy Accessories P1023-6 Mounting bracket The 90 orientation of mounting slots makes installation/removal of modules quick and easy. P1015-64 (AWG 14/16) Female Quick Connect These 0.25 in. (6.35 mm) female terminals are constructed with an insulator barrel to provide strain relief.
