Output Circuits
The output circuit has 40 points from CN10 through CN13. Two types of
circuits are provided: transistor output (24 points) and relay output (16
points). When the contact life of a relay should be considered because of
frequent ON/OFF switchings, the transistor output can be used to control
a relay mounted on an easily accessible position or a non-contact relay
SSR (solid state relay).
When connecting an inductive load to the output circuit,
connect a fly-wheel diode in parallel to the inductive load, to
suppress the surge voltage. Not using a fly-wheel diode
may damage the output circuit.
NOTE
When connecting a load with a large inrush current such as
a lamp, connect a current limiting resistance in series to the
load, so that the output current does not exceed its
maximum value. Exceeding the maximum output current
value may damage the output circuit.
