Temperature coefficient: ± 200 ppm/°C(± 111 ppm/°F) max.Digital inputsWith Standard Application Program six programmable digital inputs (common ground:24 VDC, -15 % to +20 %) and a start interlock input. Group isolated, can be divided intwo isolated groups (see Isolation and grounding diagram below).Thermistor input: 5 mA, < 1.5 kohm “1” (normal temperature), > 4 kohm “0”(high temperature), open circuit “0” (high temperature).Internal supply for digital inputs (+24 VDC): short-circuit proof. An external 24 VDCsupply can be used instead of the internal supply.Isolation test voltage500 VAC, 1 minLogical thresholds < 8 VDC “0”, > 12 VDC “1”Input currentDI1 to DI 5: 10 mA, DI6: 5 mAFiltering time constant1 msMotor control and I/O board (RMIO)
