The PureAire low cost Multichannel Digital Controller is designed to provide simple analog control or full featured digital control of toxic, LEL and oxygen deficiency monitors. It’s supplied in a 4-channel or 8-channel version and can power and operate remote gas detectors up to 100 feet away.
Capable of accepting any two or three wire gas detector, it features two user-adjustable common alarm relays that can be used for alerting personal to a gas release or to a fault from a remote gas sensor.
The Multichannel Controller also incorporates various modes of operation for taking channels off line individually for performing calibration or sensor maintenance.
Each channel can be individually designated with, PPM, PPB or %. The LCD graphical display allows for visualization of the values from all 8 channels simultaneously. It’s also capable of viewing the trends in each measuring channel in graphical form over a time period.
A graphic LCD displays monitored data as trends and engineering units. Analog 4-20mA inputs may be accepted and controlled its built-in RS-485 Modbus port allows complete data transfer.
