GE TK83PD1A
Product Name: GE TK83 Series Multi-Function Time Keeper Timer / Time Relay
Overview: The TK83PD1A is a multi-function digital time relay from GE’s TK83 “Time Keeper” family. It supports pulse timing plus delay-on-energize and delay-on-de-energize modes and is built for precise timing control in industrial automation circuits.
Technical Specifications:

- Repeat Accuracy: ±0.1% of setting
- Response Time: ≤ 20 ms
- Mechanical Life: 10,000,000 operations
- Electrical Life: 100,000 operations at full load
- Operating Temperature: –20 °C to +60 °C
- Storage Temperature: –40 °C to +85 °C
Material & Structure: Flame-retardant PC/ABS shell (UL94 V-0); nickel-plated brass terminals; FR-4 glass-epoxy internal PCB; narrow 22.5 mm body; front-wired terminals; transparent dust cover over setting knob.
Working Principle: Internal RC charging/discharging or digital counting produces the timing base; when the set time is reached, the internal relay coil is energized and the SPDT contact changes state to output the control signal.
Applications: Automated production lines, packaging machines, injection molding machines, conveyor systems, HVAC control, pump control, lighting sequence control.
Installation Requirements: Snap onto standard 35 mm DIN rail; terminal tightening torque 0.5 – 0.8 N·m; maintain at least 30 mm clearance above and below for heat dissipation.
Usage Notes: Supply voltage must match the coil marking with deviation within ±10%; avoid strong EMI environments or add RC suppressor; periodically clean the enclosure to prevent dust accumulation affecting heat dissipation.
