The RKI Beacon 410A is a four-channel gas controller that displays gas type, readings, and status for each channel. It can monitor any combination of direct-connect sensors (LEL, O2, CO2, toxic) and any 2- or 3-wire 4-20 mA transmitter. Each channel features three programmable alarm levels, two configurable relays (plus one common alarm relay), and a 4-20 mA output. A digital Modbus interface enables remote data logging via a Modbus network.

The controller is powered by 115/220 VAC or an external 24 VDC source, with an optional trickle-charge battery backup. All features are accessed via easy-to-use menus on the OLED display. The NEMA 4X enclosure is weather and corrosion resistant, and the unit is CSA and C/US approved. An optional red strobe light is available for visual alarm indication. Applications include petrochemical plants, refineries, water/wastewater treatment, and manufacturing facilities.
