4-6-2. Equivalent circuit (input)
Signal are inputted by shorting or opening input and COM terminals. A relay, switch or transisitor may
be used for this application.
4-6-3. Equivalent circuit (output)
The signal output circuit is open-collecter output of a transistor.

- Do not apply external voltage to the signal input circuit.
- Use external elements which withstand Ic=10mA.
- Leakage of external elements must be within 100μA.

- Use external power source (up to DC30V) for driving relay (vext).
- Do not short-circuit the load,such as a coil of relay ,that will break
the output transistor.
- Connect a surge absorber or a spark killer to the relay circuit as
shown in the draft so that to reduce noise trouble and extend the
life of relay.
