Time Delay Relays provide precise time-based switching for industrial control panels, machinery safety sequences and process automation. This category covers compact, DIN-rail and plug-in timers from trusted brands, led by GIC with selected models from HIQUEL and a few from Shenler, suitable for new builds and MRO.
🔧 Technical Highlights:
- Mounting formats: DIN rail, panel mount and plug-in relay base
- Timing functions (most common): on-delay (TON), off-delay (TOFF), interval/one-shot (TI), pulse-on/pulse-off, star–delta, cyclic/recycling (symmetrical and asymmetrical), staircase light, watchdog/monitoring, delay on break/make, flasher, pulse generator
- Operation: multi-function or single-function variants
- Ranges: multi-range time settings from milliseconds to hours; multi-voltage options (typ. 12–24 V DC, 24–240 V AC/DC models available depending on series)
- Outputs: SPDT/SPCO and DPDT relay contacts; transistor outputs on some models
- Status & setup: front dials or digital keys; LED indication for power, timing and relay state
- Approvals: CE and RoHS as standard on mainstream ranges
✅ Benefits:
- Reliable, repeatable timing to standardise machine sequences
- Multi-function SKUs reduce spares holding and simplify design
- Wide supply ranges ease retrofit across mixed control voltages
- Clear indication aids commissioning and fault finding
- Compatible with common industrial relay bases and sockets
🚀 Applications:
- Motor control (pump run-on, fan purge, star–delta transfer)
- Conveyor start/stop sequencing and interlocks
- Lighting control (staircase/landing timers)
- Process timing (dose, mix, dwell, cure)
- Safety-adjacent timing (not a safety device) for guard release delays
- Packaging, HVAC/BMS, materials handling and OEM machinery
Engineered for dependable time-delay control, our range helps panel builders and maintenance teams specify, buy and deploy the right timer quickly.
