S312A is a Modbus digital indicator with universal input in voltage, current, thermocouples, thermoresistors (2, 3, or 4 wire measurements), and potentiometers. The instrument allows programmable retransmission of the measured instantaneous value by the isolated analog output (voltage or active/passive current). S312A is provided with programmable filters at 20 levels to stabalize readings. Four alarms are available on the instantaneous input value (alarm type: maximum, minimum, automatically resettable or not). Alarm status is visible through four leds on the front panel.
