S312A-4-H-4R

S312A-4-H-4R is a Modbus digital indicator with universal input in voltage, current, thermocouples,, thermoresistors (2, 3 or 4 wires measurements), potentiometer. The instrument allows programmable retransmission of the measured instantaneous value by the isolated analog output (voltage or active/passive current). S312A is provided of programmable filter at 20 levels to stabilise reading. Four alarms are activable on the instantaneous input value (alarm type: maximum, minimum, automatically resettable or not). Alarms status is visible through four leds on the frontal panel.
