Yaskawa 120 Series I/O Modules - Manual (Page 83)

3.2 Digital Output Module Specifications

If using a 12/24-VDC 64-point Output Module, connect a fuse, which complies with
the load specifications, in series with the load.
A protective fuse built into the following 12/24-VDC 64-point Output Modules
does not protect the output element. If a fuse is not connected, a fire or dam-
age to the devices or output circuits may occur if the load is short-circuited or
the circuit overloaded.
Note: (1) CN2 pins A9 and B9, pins A10 and B10, pins A19 and B19, and pins A20 and
B20 are internally connected. Connect these pins externally as well. Not con-
necting them can cause malfunction.
(2) External Connection Cable
Two pairs of connectors to connect the external output signal and a 64-point I/O
Module Cable to connect to field devices are provided. For details, refer to 3.3
I/O Module Cables.
