493 – 0.5-Amp Single-Channel Relay Unit

The 493 is a single-channel relay unit, designed to allow interfacing with other building control and management systems.

The 493 signal relay unit is in a plastic enclosure, so it can be installed within a third-party equipment enclosure, electrical cabinet, or used as an in-line unit.

The relay is a solid-state, normally open signal relay, with a contact rating of 60 VAC or VDC, at a maximum of 0.5 A.

This unit must not be used to switch mains voltages.
