4.2.3 Interface Circuits

This section shows examples of SERVOPACK I/O signal connection to the host controller.
(1) Interfaces with Sequence Input Circuits
The sequence input circuit interface connects through a relay or open-collector transistor circuit. Select a low-
current relay otherwise a faulty contact will result.

(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.
