Opto Isolator

Factory installed jumper for 12VDC pull–up operation. Maximum current sink capability is 100mA per output and 350mA maximum from internal 12VDC supply.

Remove factory installed jumper from terminal P–Up. Connect an external 24VDC supply to terminals P–Up and Com. (Terminal P–Up must be positive).

Optional Opto I/O Connections

8 Optically isolated I/O connections are located at terminals 9–16 of Figure 3-4. Connections to these terminals are shown in Figure 3-11 (if the optional Opto Modules are used).
