4 digit indicator (+ bargraph) with universal input and re-transmitted output/ 24 Vdc-ac power supply. Microprocessor indicators programmable from keypad with ultrabright red LED 4 digit display and 20-segments bargraph. This family of indicators, easy to use and program, displays directly in engineering units the signals provided by the process transducers, with display range from -1999 to 9999.
The front panel with polycarbonate membrane is protected to IP44. Universal inputs for voltage, current, resistance, heating element and thermocouple signals with filter time on input signal programmable from keypad. The inputs are protected against overvoltages and overcurrents. Stabilized 20Vdc 20mA power supply for transducer. Retransmitted output with current signal 0-20 / 4-20 mA or voltage signal 0-5 / 1-5 / 0-10 / 2-10 Vdc.
Optional board with 3 relay alarms (capacity 250Vac/8A) or with 4 open collector alarms (capacity 300mA/35V) with programmable threshold values and hysteresis. Optional board for RS232 and RS485 serial interface selectable by monitoring and remote programming.
