Connecting a device to the Output terminals on the screw terminal block
Note: The Form C relay is not intended to switch AC loads directly (see the ratings below).
Form C relay ratings
Normal switching capacity | 1 | A at 30 VDC |
Maximum switching power | 30 W | |
Maximum switching voltage | 60 VDC | |
Maximum switching current | 2 | Adc |
Maximum carrying current | 2 | Adc |
Surge ratings | 2 kV per Bellcore; | |
| 1.5 kV per FCC part 68 | |
If you are connecting two Dry Contact I/O Accessories to a
Management Card 2, you have two options:
• Connect a device to the Output terminals for each Dry Contact I/O Accessory separately.
• Connect the Dry Contact I/O Accessories in the same circuit to implement AND or OR logic (see the diagram to the right). For example, if one Output changes state when the host reports a Replace Battery alarm and the other Output changes state when the host reports a Fault alarm, you can connect the Dry Contact I/O Accessories so that the device detects a change in state when only one alarm occurs (OR logic) or when both alarms occur simultaneously (AND logic).
