Optional DIO Cables
The cables that connect to the input and output connectors on the sDIO can be ordered as
a set of four cables: two input cables and two output cables. These cables have a mating
plug on one end and unterminated flying leads on the other end. The wire size of the
Adept cables is 0.18 mm
2 (24 AWG). You can use these cables to connect to the digital
inputs/outputs in your system or to a wiring block.
To comply with IEC 1131, if you choose to supply a wiring block, it should be capable of
accepting wire in the range of 0.18 mm
2 (24 AWG) to 2.0 mm 2 (14 AWG).
Labeling Cables
The X3 and X4 input connectors on the front of the sDIO are similar except that X3 handles
the group 1 and group 2 input signals and X4 handles the group 3 and group 4 input
signals. The optional digital input cables can be connected to either X3 or X4. Make sure to
clearly label the cables once you have completed your installation so that the cables do not
get swapped by mistake; see the warning below.
The X1 and X2 output connectors are also similar except that X1 handles the group 1 and
group 2 output signals and X2 handles the group 3 and group 4 output signals. The
optional digital output cables can be connected to either X1 or X2. Make sure to clearly
label the cables once you have completed your installation so that the cables do not get
swapped by mistake; see the warning below.
WARNING: Make sure to clearly label the X1 to X4 digital
I/O cables so that they are always plugged into the correct
connector. Swapping the X3 and X4 or X1 and X2 cables
could cause damage to your equipment. Depending on the
installation, this could potentially cause injury to
personnel in the area.
