2-4. External Input/Output (Amphenol Connector) Connection
The adaptable connector (plug) is DDK-manufactured 57-30140 (included) or its equivalent.
Connect referring to the internal circuit diagram shown below.
For input
The signal input/output circuit inputs signals by short-circuiting and opening the input and
COM terminals.
Short circuits are made by contact (relay, switch, etc.) or noncontact (transistor, TTL open
collector output, etc.)
For output
The signal output circuit outputs signals by means of a transistor open collector.

・
Use external power source 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.
