8112 – 4 Optically Isolated Inputs/4 Form C Outputs

The SeaDAC Lite 8112 provides 4 optically isolated inputs and 4 SPDT Form C
relay outputs. Inputs can range from 5-30VDC and provide 300V isolation to ground,
while the Form C relays switch up to 60VDC @ 5A or 250VAC @ 6A. Each Form
C relay has a discrete common and includes normally-open and normally-closed
contact connections. Each pair of inputs shares a common. Status LEDs display I/O
activity and field wiring is simplified via 3.5mm field removable terminal blocks.
