Time Delay Relays Dedicated - Delay-on-Make TH1 SERIES Description The TH1 Series is a solid-state relay and timer combined into one compact, easy-to-use control. This highly reliable device eliminates the need for a separate solid-state relay. When mounted to a metal surface, it can switch load currents up to 20A steady state, and 200A inrush. 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 FEATURES BENEFITS Repeat Accuracy + / - 2%, Microcontroller based Factory calibration + / - 5% Wiring Diagram Compact, low Allows flexiblility for OEM applications and reduces L1 N/L2 cost design labor and component costs High load currents up Allows direct operation of motors, lamps, and to 20A, 200A inrush heaters directly without a contactor No moving parts to arc and wear out over time and V = Voltage Totally solid state encapsulated to protect against shock, vibration, and encapsulated S1 = Optional Low Current and humidity Initiate Switch Metalized L = Load Facilitates heat transfer for high current applications mounting surface R is used when external T adjustment is ordered.
