Analog Relay Board – ARB2 is a gas measuring and warning controller board based on state-of-the-art technology for continuous monitoring of the ambient air to detect toxic, combustible and refrigerants gases.
The ARB2 is designed for the connection of one 4-20 mA analog sensor, e.g. of the μGard®2 MC2 series. The board monitors the measured value and activates the alarm relays if the set alarm thresholds for pre-alarm and main alarm are exceeded. In addition, the value is provided at the analog output as 4-20 mA signal.
Options such as LCD display and warning unit (WAO) ensure proper adaptation to the wide range of applications in process control technology
