H5CN-XCN

What type of device is this?

It is an industrial digital timer designed to control an electrical output after a preset time interval.

What timing range does it provide?

The timer can be set from 1 second up to 99 minutes and 59 seconds.

How is the operating time configured?

The required time is entered using front-mounted thumbwheel switches, allowing the setting to be viewed and adjusted directly.

Does the display count upwards or downwards?

The H5CN-XCN uses an UP display, meaning the displayed value increases from zero towards the selected time.

Which output operating mode is used?

It uses an N-mode power-ON delay. The timer begins counting when operating power is applied, and the control output changes state when the set time expires.

What type of control output is fitted?

The unit has an SPDT relay contact output rated at up to 3 A at 250 VAC for a resistive load.

What input functions are available?

Reset and gate inputs are provided. These use no-voltage input signals with a minimum input width of 20 milliseconds.

What supply voltage does it require?

Versions were produced for 100–240 VAC and 12–48 VDC supplies. The voltage rating printed on the unit should always be checked before installation.

How is the timer mounted?

It supports both flush panel mounting and surface mounting, making it suitable for control panels and industrial enclosures.

What electrical connection does it use?

The timer connects through an 8-pin round socket. The socket terminal arrangement and existing panel wiring should be checked before fitting.

What are its approximate front dimensions?

The timer has a compact 48 × 48 mm front profile commonly used for panel-mounted industrial timing devices.

What environmental conditions can it operate in?

It is rated for operation from -10°C to 55°C in environments without icing or condensation, with an operating humidity range of 35% to 85%.

How accurate is the timing operation?

For a power-ON start, the specified accuracy is within ±0.01% of the set value plus 0.05 seconds. For a reset start, it is within ±0.005% plus 0.03 seconds.

What applications is it commonly used for?

Typical uses include delayed machine start-up, timed process stages, conveyor sequencing, pump control, heating cycles and general control-panel automation.

Is there a modern replacement option?

For the 100–240 VAC version, Omron identifies the H5CC-L8 100–240 VAC as the recommended replacement. For the 12–48 VDC version, the corresponding option is the H5CC-L8D. Electrical connections, dimensions and operating settings should be compared before substitution.
