(2) Interfaces with Output Circuits
The SERVOPACK signals use the following types of output circuits. Construct an input circuit on the host
controller side to match the output circuit.
• Connecting to a Photocoupler Output Circuit
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 max.
• Current: 50 mA DC max.
