3 Digital I/O Specifications

3.2.7 12/24-VDC 64-point Output Module

3-52

3) The following diagram shows an example of terminal connections.

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) CN1 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) Connector for External Connections (included)

Connector: FCN-361J040-AU (soldered) (manufactured by Fujitsu Ltd.)
Cover: FCN-360C040-B (manufactured by Fujitsu Ltd.)

(3) Recommended Wires

Use wires of 0.26 mm

(AWG23) to connect to each connector pin.
