H3CA-A Description

Short technical summary and product information.

The Omron H3CA-A is a multi-mode, multi-range solid-state timer designed for a variety of applications. It features a digital set with a broad time delay range spanning from 0.1 seconds to 9990 hours, allowing for precise timing control. The unit is housed in a compact, 1/16 DIN plug-in form factor, making it suitable for space-constrained control panels.

 

Key operational features include an easy-to-read LCD display for time remaining and output status indicators. The timer supports multiple control modes and utilizes thumbwheel switches for selecting time units, control modes, and time limit settings. It operates on a wide supply voltage range of 24 to 240 VAC or 24 to 240 VDC, with a power consumption of 3VA (AC) or 3W (DC).

 

The output stage consists of a mechanical relay with an S.P.D.T. (1 Form C) contact configuration, rated for 3A at 250VAC. This relay offers a mechanical life of 10,000,000 operations. The timer is designed for various mounting options, including panel, track, and surface mounting, and features an 11-pin plug-in termination style.

 

Environmental specifications include an operating temperature range of -14 to 131 degrees F and humidity tolerance of 35 to 85% RH. The timer is UL Recognized and CSA Certified, indicating compliance with relevant safety standards.
