Omron H3DT Series Timer Relay, 1 to 120s Time Range, 100/120V AC Supply Voltage - H3DT-HCS 100-120VAC

This timer relay provides adjustable time-delay control for industrial automation and control panels. It accepts an AC supply and delivers timed switching via a single-pole double-throw contact arrangement, suited to DIN-rail mounting in panel installations. The unit is intended for professionals requiring compact, panel-mounted time-delay functions within electrical and mechanical systems.

Features and Benefits:

• 1 to 120 s adjustable timing range for flexible delay settings
• SPDT contact rated at 5A for moderate load switching
• Screw terminals for secure electrical connections
• DIN-rail mounting for Rapid installation in control panels
• 250V switching capability to handle common control voltages
• Dial timing adjustment for quick, on-site calibration

Applications

• Suitable for sequencing control in assembly automation
• Ideal for time-delay functions in motor starter circuits
• Used for control-logic timing in HVAC systems
• Can be used for staged lighting or signalling control
• Suitable for marine or offshore control panels requiring Compact relays

What supply voltages does it accept?

It operates from AC mains at 100–120V and is also specified for use with a 240V DC supply rail.

How many independent timing functions are available?

The unit provides a single timing function with adjustable duration across its full range.

What environmental temperature limits must be observed?

The relay is rated to operate down to −20 °C and up to 60 °C ambient temperature.

What standards or approvals apply to its electrical safety?

It meets multiple industry standards including EN and IEC requirements Plus regional certifications for use in industrial installations.

How many switching elements are provided and how are they configured?

There are two contact elements arranged as one SPDT switching set to enable changeover control.
