The RKI Beacon 110 is a single-channel gas controller that accepts any 2- or 3-wire 24 VDC 4-20 mA transmitter. It displays gas type and concentration on a digital backlit display, with 10A-rated relays strong enough to power external alarms directly. The controller includes a 24 VDC 400 mA max output to operate sample draw adapters or accessories.

When purchased with sensors, the Beacon 110 is factory calibrated and ready to use. Sensors can be mounted directly to the controller housing or wired remotely. The unit features a 94 dB audible alarm with two programmable levels, a built-in trouble alarm with relay, and an external reset switch. It is housed in a weatherproof NEMA 4X enclosure and can be powered by 115/220 VAC or 24 VDC. Applications include petrochemical plants, refineries, water/wastewater treatment, and parking garages.
