The 24-VDC external power supply capacity must be 50 mA minimum.
The SERVOPACK input circuits use bidirectional photocouplers. Select either a sink cir-
cuit or source circuit according to the specifications required by the machine.
The connection examples in Ä Chap. 5.6.3 ‘I/O Signal Wiring Examples’
page 120 are for sink circuit connections.
