Input Port Specification
Number of input ports: 8
Input voltage: DC 24 V
Input current: 7 mA or less
Insulation method: Photo-coupler insulation
Adaptive connection: Output of an external device (sync output)
Output Port Specification
Number of output ports: 8 (sync output)
Rated load voltage: DC 24 V
Maximum load current: 8 mA per port (64 mA or less in total)
Leakage current: 0.1 mA or less
Insulation method: Photo-coupler insulation
Adaptive connection: Input of an external device
The input ports are designed
for connecting to non-contact
output such as transistor.
When connecting a mechani-
cal contact (switch, relay, etc.),
be sure to use a minimal- cur-
rent product. Leakage current
of a non-contact circuit (OFF)
connected to each input port
must be 1 mA or less.

Never apply the load more
than stated above.
The output ports are designed
for connecting to the load such
as transistor. When connecting
the inductive load (relay, etc.),
be sure to apply a protection
diode for absorbing back EMF
to the coil. Inappropriate con-
nection may cause damage to
the circuit.
