Omron DIN Rail Timer Relay 2-Contact SPDT Power-Off Delay 100 - 120VAC, 240VDC, 1 - 120s H3DT

The Omron H3DT-HCL 100-120VAC is a DIN rail timer relay specifically designed for industrial applications, featuring a 2-contact SPDT output configuration. This timer relay offers broad compatibility for automation panels, supporting both AC and DC supply modes: 100 - 120VAC and 240VDC. The adjustable timing window, ranging from 1 to 120 seconds, allows engineers and electricians to implement precise delay operations for sequence control, interlocking, and process control tasks.

Installation is simplified using push-in terminals, enabling rapid, tool-free conductor wiring and consistent assembly in panel environments. The SPDT contact arrangement enables changeover between separate circuits, avoiding the need for additional relays when routing signals or power.

The H3DT-HCL 100-120VAC provides robust electrical performance, accommodating loads up to 5A at a maximum switching voltage of 250VAC. Its mode is focused on power-off delay, making it ideal for applications requiring controlled shutdown or post-operation lag. Environmental resilience is ensured, with operational capability from -20°C to 60°C and protection ratings of IP30 and IP20 against dust and incidental panel ingress.

Its compact physical form, with dimensions of 100mm height, 17.5mm length, and 90mm width, enables dense panel installations without sacrificing accessibility. The timer series meets several international standards and approvals, including UL 508 and EN 61812-1, which confirms suitability for use in regulated industrial facilities.

Applications include sequence control in conveyor and material handling systems, timed operation of motor starters, delay functions in HVAC panels for fan or compressor startup, and staged lighting control in factories. The timer relay is also commonly used in relay logic safety circuits for reset sequences and fail-safe delays.

Push-in terminals reduce wiring time and promote error-free installations, while the SPDT configuration offers flexible switching between normally open and normally closed paths. The device supports fine timing adjustment via dial and comes with clear capability for integration into a wide array of electrical automation panels.
