Note
• The output circuit is composed of open collector transistor outputs in the Darlington
connection, and connect to relays or photocouplers.
• There exists collector to emitter voltage, V
CE
(SAT) of approx. 1V at transistor-ON, due to the
Darlington connection of the output or. Note that normal TTL IC cannot be directly connected
since it does not meet VIL.
• There are two types of output, one (2 systems of SO5, SO6) which emitter side of the output
transistor is independent and is connectable individually, and the one (4 systems of SI1 to
SI4) which is common to – side of the control power supply (COM–).
• If a recommended primary current value of the photocoupler is 10 mA, decide the resistor
value using the formula of the below gure.
• When accepting the output signal through a logic circuit, e.g. gate, inuence from noises
should be prevented.
For the recommended primary current value, refer to the data sheet of the equipment and
photocoupler to be used.
