Description
Indicates the operating status of the power supply module.
On: Normal operation
Off: Power-off, power failure, or hardware failure ( MELSEC iQ-R CPU Module User's Manual (Application))
■When mounting the module on the main base unit
The contact turns on when the entire system operates normally. (M4 screw)
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.
When the remote head module is mounted, this contact turns off when moderate or major error (including reset)
occurs.
■When mounting the module on the extension base unit
The contact is off at all times.
When the module is mounted on a redundant power supply extension base unit, the following operation is
performed:
• The contact turns on when the power supply module operates normally. (M4 screw)
• This contact turns off (opens) when the power supply module fails, the power is not supplied, or the fuse is
blown.
A functional ground terminal connected to the shield pattern of the printed circuit board (M4 screw)
A functional ground terminal for the power supply input filter. 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) ( Page 85 Performance Specifications of Power Supply Module)
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)
The power is supplied to a device through the external wiring.
