Supply
|
| Voltage |
24 Vdc nom (20 to 30 Vdc) reverse polarity protected, double terminal blocks for redundant power supply, with OR diodes to mix supply voltages. |
| Connection |
by polarized plug-in disconnect screw terminal blocks to accommodate terminations up to 2.5 mm2. |
| 2 LEDs indication |
green color, one for supply 1 and one for supply 2. |
| Protection fuse |
4 A time lag (spare fuse provided on Termination Board). |
Fault detection
|
| 1) Preventive – abnormal supply voltage |
supply 1 or supply 2 is < 18 Vdc (Under Voltage, UV) or > 30 Vdc (Over Voltage, OV). |
| 2) Critical – abnormal supply voltages or cumulative fault |
both supplies are in under (< 18 Vdc) or over (> 30 Vdc) voltage condition OR cumulative fault indication (about presence of short or open field circuit for any DO channel). |
| LED fault signaling (for both case 1 and 2) |
2 red LEDs (UV and OV of supply 1); 2 red LEDs (UV and OV of supply 2); a cumulative fault red LED. |
| Relay fault signaling (one for each case 1 or 2) |
a voltage free NE SPDT – 1 Form C relay contacts (de-energized in fault condition) |
| Contact material |
AgCdO. |
| Contact rating |
2 A 36 Vac 72 VA, 2 A 48 Vdc 80 W (resistive load). |
| Mechanical / electrical life |
30 * 106 / 1 * 105 operation, typical. |
| Coil status LED indication |
yellow color, turn on when coil is energized. |
| Connection |
by polarized plug-in disconnect screw terminal blocks to accommodate terminations up to 2.5 mm2. |
