Wiring Servo Relay Units Section 3-4
Example Servo Relay
Unit Wiring
When Servo Relay Units for the FQM1 are used, the I/O power supply is pro-
vided from terminals 20-0, 21-1, and 60-40. The only additional wiring
required are the connections between the signals, as shown in the following
diagram.
