Open Collector Outputs
The open collectors are labeled OC9 thru OC16. Make your connection between
the desired open collector and ground “GND”. The open collector (OCx) output for

ger input, TTL/CMOS logic, or relay. External pull-up resistors may be required in
some installations. NOTE: The open collectors are rated at up to 6 VDC @ 50 mA.
