(b) Photocoupler Output Circuit
Photocoupler output circuits are used for servo alarm (ALM), brake interlock (/BK), 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 photocoupler output circuits
are as follows.
• Voltage: 30 VDC
• Current: 50 mA DC
