This contact turns off (opens) in the following cases:
• When the power supply module fails
• When the power is not supplied
• When a stop error (including reset) occurs in the CPU module
• When the fuse is blown
In a multiple CPU system, the contact turns off when a stop error occurs in any of the CPU
modules.

• This contact turns off (opens) when the power supply module fails, the power is not
supplied, or the fuse is blown.
A ground terminal connected to the shield pattern of the printed circuit board. This terminal
is a functional ground terminal. (M4 screw)
A ground terminal for the power supply input filter. This terminal is a functional ground
terminal. For AC input, the terminal has one-half the potential of the input voltage. (M4
screw)
A power input terminal for the power supply module. The power supply to be connected
differs depending on a power supply module. (M4 screw) (Refer to the specifications list.)
A protective cover for the terminal block.
Shows the production information (16 digits) of the module.
Used for a device that requires a supply of 24VDC. (M3.5 screw)
