S312A-4-L-4R / S312A-4-H-4R Line
Advanced Analog Indicators
4-Digits Display with 4 relay outputs
Universal input: voltage, current, thermocouples,, thermoresistors (2, 3 or 4 wires
measurements), potentiometer.
Programmable retransmission of the measured instantaneous value by the
isolated
analog output (voltage or active/passive current).
Filter programmable at 20 levels to stabilise reading.
Temperature measurement displayable in Celsius or Fahrenheit degrees.
Cold junction compensation in case of thermocouple input.
4 Digits display.
Four alarms are activable on the instantaneous input value (alarm type: maximum,
minimum, automatically resettable or not).
Alarms status visible through four leds on the frontal panel.
Rs485 serial communication with MODBUS RTU protocol, maximum 32 nodes.
Four relay outputs for alarms signalling.
Easy navigation on the programming Menu by three buttons on the frontal panel.
Quick configuration of the alarm thresholds by the Quick Alarms Menu.
Disturbance Rejection at 50 and 60 Hz.
Display contrast settable.
Four relay output: default state for out3 and out4 are settable by internal jumper
