This dual 5 digit display indicator will allow you to easily display two process variables (4 to 20 mA from sensors or transmitters), perform one of four basic math functions of the signals and transmit the result as a 4 to 20 mA signal for further display or logging.

Each display can be configured with separate decimal point and scaling. The meter can add, subtract, multiple or divide the two input signals. Each of four alarm relays can be set to monitor either input or the math function result, with delay and hysteresis settings.
