Note: The maximum allowable voltage and current capacities for open-col-
lector output circuits are as follows.
• Voltage: 30 VDC max.
• Current: 20 mA DC max.
• Connecting to a Photocoupler Output Circuit
Photocoupler output circuits are used for servo alarm, servo ready, and other sequence
output signal circuits.
Connect a photocoupler output circuit through a relay or line receiver circuit.
Note: The maximum allowable voltage and current capacities for photocou-
pler output circuits are as follows.
• Voltage: 30 VDC max.
• Current: 50 mA DC max.
