3 Digital I/O Specifications

3.2.3 12/24-VDC 8-point Output Module

3-34

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

If using a 12/24-VDC 8-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 8-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) Crimp Terminals

Use M3 crimp terminals for the terminal block.

(2) Recommended Wires

Use wires of 0.8 mm

(AWG18) to 0.2 mm

(AWG24) to connect to the terminal

block.

(3) A blown-fuse detection circuit is not built into the circuit. If no output current

flows while the output signal indicator is lit under the rated voltage, the built-in
fuse may be blown. The built-in fuse must be replaced by a Yaskawa service
representative.
