Ships in 6 - 8 weeks
$2,500.00 - $2,650.00


The Beacon 200 is a two channel gas detection control unit. It can accept direct connect sensors (sensors not included) for LEL combustibles, oxygen, hydrogen sulfide, and carbon monoxide as well as other gases. This economical controller is made to receive signals from two fixed gas detection units and works with RKI Direct Connect Sensors or M2- or S2-Series Sensor/Transmitters. The Beacon 200 works with any 4-20 mA transmitter (2 or 3 wire, 24 VDC) and sensors can be mounted remotely from the controller or directly on the housing. The microprocessor-controlled Beacon 200 has two built-in 10 amp-rated relays strong enough to activate most external alarms and sirens without the use of external slave relays. The backlit readout on the Beacon 200 displays gas type and concentration, while the housing itself is rated NEMA 4X for indoor or outdoor use. RKI Instruments offers the industry's widest selection of gas detection sensors allowing the Beacon 200 to be used for almost any gas detection application.

Applications: Petrochemical plants, Refineries, Water & wastewater treatment pants, Pulp & paper mills, Gas, telephone, & electric utilities, Parking garages, Manufacturing facilities, Steel, Automotive, HVAC
