Notes for output wiring
External power supply
– Relay outputs
Use an external power supply of 30 V DC or less or 240 V AC or less for
loads.
– Transistor outputs
For driving the load, use a power supply of 5 to 30 V DC that can output
current two or more times the rated current of the fuse connected to the
load circuit.
Voltage drop
The voltage drop at ON of the output transistor is approx. 1.5 V. When driv-
ing a semiconductor element, carefully check the input voltage character-
istics of the applied element.
Response time
The transistor OFF time is longer under lighter loads. For example, with a
load of 40 mA at 24 V DC, the response time is approx. 0.3 ms. When
response performance is required under lighter loads, install a resistor in
parallel with the load to increase the load current of the output.
m
Protection of the outputs
Protection circuit for load short-circuiting
When a load connected to the output terminal short-circuits, the printed
circuit board may be burn out.
Fit a protective fuse on the output circuit.
Protection circuit when inductive load is used
– Relay outputs
When an inductive (for example a relay or a solenoid) load is connected
to a
DC voltage
, connect a diode in parallel with the load.
Use a diode (for commutation) having the following specifications:
– Reverse dielectric strength: over 5 times the load voltage
– Forward current: Load current or more
When an inductive load is switched by a relay output to an
AC voltage
,
connect a surge absorbing element (CR composite part, i.e. surge killer
and spark killer) in parallel with the load.
Use a surge absorber having the following specifications:
– Rated voltage: 240 V AC
– Resistance value: 100 to 200
– Electrostatic capacity: approx. 0.1 μF
– Transistor outputs
When an inductive (for example a relay or a solenoid) load is connected,
connect a diode in parallel with the load.
Use a diode (for commutation) having the following specifications:
– Reverse dielectric strength: 5 to 10 times the load voltage
– Forward current: Load current or more
