S311A-4-H

S311A-4-H is an universal display with analog input (mA, V, PT100, TCs, Ohm) order codes that allows to view the istantaneous value (engineering units), retransmit it through an isolated analog output and, by the optional board, have N.2 relay alarms and Modbus interface. Furthermore the unit allows to integrate the input and totalize it into the internal memory. It is available with 4,6 or 8 digits and an 7+4 digits (double line).

• Universal input: voltage, current, thermocouples,, thermoresistors (2, 3 or 4 wires measurements), potentiometer.
• View of the instantaneous and/or integrated input value.
• Programmable retransmission of the measured instantaneous value by the isolated analog output (voltage or active/passive current).
• Retransmission of the integrated value by the digital output (Open Collector). isolated
• Integrator value is saved on non-volatile memory.
• Filter programmable at 20 levels to stabilise reading.
• Temperature measurement diplayable in Celsius or Fahrenheit degrees.
• Cold junction compensation in case of thermocouple input.
• Integrator Reset by digital input, buttons pressure or Modbus register.
• 4, 6, 8 or 11 (4+7) Digits display.
• In case of optional card use, two alarms are activable on the instantaneous input value (maximum, minimum, automatically resettable or not).
• Alarms status visible through two leds on the frontal panel.
• RS485 serial communication with MODBUS RTU protocol (by optional board), maximum 32 nodes.
• Two relay outputs (available on the optional card) 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.
