Omron H3M Series Surface Solid State Timer, 110 V dc 200 V, 220 V, 240V ac, 0.05 → 0.5 min, 0.05 → 0.5 s,

Omron H3M Series Solid State Timer, 200V Supply AC Voltage, DPDT Contact Configuration - H3M AC200/220/240 B

This solid-state timer provides precise timing control for industrial control panels and automation systems. It is designed to switch and sequence circuits in environments where a compact, surface-mounted timing relay is required. The unit supports a range of AC supply voltages and an alternative DC supply, making it adaptable to varied electrical setups in electronics and mechanical installations.

Features and Benefits:

• Compatible with 200V, 220V, 240V AC supplies for versatile integration
  Accepts 110V DC supply for systems using DC control rails
  Dual-pole changeover contact arrangement for flexible switching
  PCB Terminal mounting for neat panel and board installation
  Multifunction timing offers multiple operating modes for control tasks
  Contact rating 0.15A to suit low-current signal switching

Applications

• Suitable for sequencing control in automation panels
  Ideal for timing circuits in industrial electronic assemblies
  Used with relay logic for machine start/stop routines
  Can be used for interlock timing in electrical control cabinets

What approvals support use in regulated installations?

The unit carries CSA, UL and LR approvals, allowing installation where recognised safety listings are required.

What operating temperatures can it tolerate during continuous use?

It operates reliably across a -10 to +50°C ambient range for typical industrial environments.

How is the timer mounted and connected in a control panel?

It is a surface-mount design with PCB Terminals intended for direct board or panel-mounted Terminal connections.

Which functional capability allows replacement of electromechanical timers?

Its solid-state multifunction behaviour with DPDT contacts enables it to substitute mechanical timing relays in low-current applications.

What physical footprint should engineers allow for on layout drawings?

The device occupies a Compact enclosure measuring 50mm length, 40mm width and 67.1mm height for panel space planning.
