How to Connect an Interface Connector
When connecting the Module to an external device, you can
use the supplied connector plug.
To wire the Module, strip the sheath about 9 - 10mm from an
end of the wire and insert the exposed wire into an opening.
Tighten the screw to fasten the inserted wire. Applicable
wires are AWG28 - 16.

Input section
Figure below shows the input equivalent circuit for the interface
section of this product.
The signal input section consists of an Optocoupler isolated
input (compatible with both current sink output and current
source output). An external power supply is therefore
required to drive the input section of this module. The power
requirement for the <DIO-4/4(FIT)GY> or <DI-8(FIT)GY> is
about 8 mA per input channel at 24 VDC (about 4 mA at 12
VDC).

Output section
Figure below shows the output circuit for the interface section
of this product. The signal output section consists of an
Optocoupler isolated open collector output (current sink type).
An external power supply is therefore required to drive the
output section of this module.
The maximum output current rating per channel is 150 mA for
this product (at 12 - 24 VDC) or 50mA for this product (at 36 -
48 VDC). A surge voltage protection circuit (zener diode) is
provided for the output transistors of this module. When the
module drives relays, lamps, and other induction loads,
however, another surge voltage countermeasure should be
provided on the load side.
