2.4.6.2 AC VOLTAGE INPUTS
2.4.6.3 CONTACT INPUTS
2.4.6.4 REMOTE INPUTS
2.4.6.5 ANALOG INPUTS
VT Ratio 1.0 to 1500.0 in steps of 0.1
Rated Voltages 500 Vac
Metering range: From 2 to 500 Vac
Relay Burden: 0.05 VA at 120 Vac (50 or 60 Hz)
Voltage Withstand: Continuous at 500 V to neutral
1 min/hr at 800 to neutral
VAC inputs do not need varistors, as the impulse test is applied to 100% of the transformers
Input Activation Voltage Threshold: 1 to 230 Vdc in steps of 1 V (selectable by setting)
Impedance: > 100 kOhm
Maximum error:
±10% setting ± 2.5 V
Load for voltage supervision inputs: 2 mA + V/100 kOhm
Voltage threshold for voltage
supervision inputs
< 10 V (fixed)
Debounce Time: 1 to 50 in steps of 1 ms
Recognition time: < 1ms
Timing resolution: 1 ms
For Input Activation Voltage Threshold and Debounce Time there is a single setting for all inputs in the same
group (inputs sharing the same common).
Input Type and Delay Input Time are not grouped; there is a different setting for each input.
Input Type Positive-Edge / Negative-Edge / Positive/ Negative
Delay Input Time 0 to 60000 ms in steps of 1 ms (Input signal time delay)
Number of input points: 32, configured from 64 incoming bit points
Number of remote devices:
16
Default states on loss of comms: On, Off, Latest/on, Latest/off
Current Input (mADC): 0 to -1; 0 to +1; -1 to +1; 0 to 5; 0 to 10; 0 to 20; 4 to 20 (programmable)
Conversion Range:
-1 to +20mA
Accuracy: +/- 0.2% of full scale
Type: Passive
