9-2. Equivalent Circuit (Input)
A signal is inputted to the signal input circuit by short-circuiting or opening the input terminal and
the COM terminal. Short-circuiting is effected by means of a contact (such as a relay or a switch) or
a noncontact (such as a transistor or an open-collector TTL).
9-3. Equivalent Circuit (Output)
The signal output circuit is open-collecter output of a transistor.

- Do not apply external voltage to the signal input circuit.
- The external element is required to withstand Ic=10mA.

- 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 speark killer to the relay
circuit as shown in the draft so that to reduce noise trouble
and extend the life of relay.
Noise trouble can be reduced, and the relay’s life can be
extended.
