Product Description:

Danaher's HG100A6 Electromechanical time delay relay features a mechanical 24-hour dial-based timing mechanism. This relay's square panel-mount front and rounded rear make it compatible with the majority of DIN-style panels. For electrical switching systems that need timed control throughout daily cycles, the relay is a good choice.

A 24-hour dial advances by means of a motor-driven gear system that activates cam-operated switches, allowing the HG100A6 electromechanical time delay relay to function. At its highest point, the dial displays the ON position, and a red pointer indicates the current switch position. To make changes by hand, the relay comes with a colored knob. Timing ranges from zero to thirty minutes or twenty-four hours are available in different models. The relay can handle currents of up to 120 volts AC at 50 or 60 Hz. We set up the wiring using an octal base with eleven pins. Connectors 4-5 and 7-8 are for the ON state, whereas 9-5 and 10-6 are for the OFF state, in terms of pinout. Front panel flanges with screw fittings are used for mounting. Interconnected motor, contacts, and terminals are part of the inner workings. Dial rotation is transformed into switching actions that meet the timing requirements of industrial automation systems by means of the geartrain and switch assembly.

The precise mechanical timing of HG100A6 Electromechanical time delay relay's repeat operations is guaranteed by its cam switch assembly. Some of the contact ratings are 1/3 HP at 120V or 1/2 HP at 240V, and 10A at 120/240V AC for resistive loads. A separation exists between the power input terminal and the output contacts used to control external loads. The socket-mounted panels may be quickly replaced thanks to the base design.

Frequently Asked Questions about HG100A6:

Q: Does HG100A6 support both resistive and motor loads?

A: Yes, it handles 10A resistive loads and fractional horsepower motor loads. The contact ratings support stable performance in varied electrical systems.

Q: How does the 11-pin base benefit HG100A6 users?

A: The 11-pin octal base simplifies wiring. It enables socket-based installation and fast replacement without rewiring.

Q: Why do pins 4-5 and 7-8 indicate an ON state in HG100A6?

A: These pins connect to the cam-operated contacts. They close circuits during the ON periods set on the dial.

Q: Does HG100A6 support both 0–30 min and 24-hour ranges?

A: Yes, it comes in variants offering either a timing range. This allows users to choose based on short or long delay requirements.

Q: How does the pointer help in HG100A6 timing adjustment?

A: The red pointer marks switch positions on the dial. It provides a visual reference to set exact activation times.
