3) I/O Signal Cables
Do not allow foreign matter such as cable chips in the Modules or Mounting Bases.
Foreign matter in the Modules or Mounting Bases may cause fire, failures and/
or malfunctions.
a) There are five types of AC I/O Modules. See
Table 6.5
.
To connect these I/O Modules to signal line, use I/O signal cable of the size listed in
Table 6.5
. The cables differ in their permissible current capacity depending on the
conditions of use, such as the ambient operating temperature, so check the condi-
tions of use and select a cable of appropriate size.
b) M3 Phillips screws are used in the external connection terminals. Accordingly, use
crimp terminals for M3 Phillips screws for the Module-end of I/O signal cable.
4) Protective Fuses
If using an Output Module, connect a fuse that complies with the load specifications in
series with the load.
• 100/200-VAC 8-point Output Module: Model No. JAMSC-120DAO83000
• 100/200-VAC 16-point Output Module: Model No. JAMSC-120DAO84300
• Relay Contact 16-point Output Module: Model No. JAMSC-120DRA84300
If a fuse is not connected, a fire or damage to the device or output circuit may occur if
the load is short-circuited or the circuit overloaded.
6.2.3
Wiring DC I/O Modules
This section explains how to connect a power supply cable and an I/O signal cable
to a DC I/O Module.
1) DC Power Supply Specifications
a) As shown in Examples 1 and 2 later in this section, it is necessary to supply external
DC power (12/24VDC) to the DC I/O Modules listed in the following table to power
input signals and drive loads.
