General Monitors 610A Four Channel Control Module Combustible Gas Monitor Instruction Manual

The Model 610A Controller is a four-channel system designed to continuously monitor for potential explosive concentrations of most combustible gases/vapors. Normally, only a periodic calibration check is needed to assure dependable performance. The system operates in the range of 0-100% LEL (Lower Explosive Limit) and is calibrated for a particular gas or vapor. Each channel has constant current sensor drive circuit, LED indicators for High, Low, Fault, Calibration, and Setup, Mode Button, Digital Display in %LEL, High, Low and Fault relays. The system can be powered by AC or DC power.

Frequently asked questions

The Model 610A Controller has four channels.

The Model 610A Controller operates in the range of 0-100% LEL (Lower Explosive Limit).

Any GMI low temperature catalytic bead combustible gas sensor assembly may be used with the system.

The system operates on nominal line power of 115 VAC, 50/60 Hz. Primary DC power may be used instead. Use any 24V nominal direct current supply with a minimum rating of 2 amperes.

The analog output terminals are located on the rear panel. The analog output is 0 – 21.7mA into a maximum 300-Ohm load.

Remote reset connections are made to rear panel terminal board connections RESET and the 24VDC (-) terminal. If a remote reset switch is used, it must be a “normally open, momentary action” type.
