Overview
The IDEC RTE-P2AD24 is a signal-triggered multifunction electronic timer relay engineered for industrial automation, HVAC systems, and general control applications. This 24VAC/DC-powered device provides exceptionally flexible timing control with switchable functions and adjustable delay ranges. The compact 11-pin plug-in format and dual DPDT (2 Form C) contact configuration make it ideal for retrofits and new installations in standard relay sockets.
Key Features
- Six Distinct Timing Functions: ON-delay, OFF-delay, cycle OFF, cycle ON, signal ON/OFF delay, and one-shot—selectable via external switches
- Broad Delay Range: 0.1 seconds to 600 hours across 20 selectable time ranges
- Dual DPDT Contacts: 2 Form C delayed outputs rated 10A @ 240VAC or 30VDC; 1/6 HP @ 120VAC; 1/3 HP @ 240VAC
- High Repeat Accuracy: ±0.2% timing accuracy ensures consistent performance across thousands of cycles
- LED Status Indicators: Power and timing-out LEDs for quick visual diagnostics
- Universal Mounting: Plug-in socket or 45 mm panel-mount adaptor compatible; DIN rail or surface options
