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 |
Preventive - abnormal supply voltage
|
supply 1 or supply 2 is < 18 Vdc (Under
Voltage, UV) or > 30 Vdc (Over Voltage, OV).
|
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) |
Type
|
