Name
This is the terminal block for inputs such as the power supply input and
24-VDC inputs.
Input status is displayed. An indicator will be ON when the input is ON.
Used to connect to a personal computer for programming and monitor-
ing by the CX-Programmer for CP1E.
By turning an analog adjuster, it is possible to adjust the value of A642
or A643 within a range of 0 to 255.
Refer to Section 17 Built-in Functions in the CP1E CPU Unit Soft-
ware User's Manual (Cat. No. W480).
The CPU Unit's operating status can be confirmed with this indicator.
Refer to CPU Unit Status Indicators (Page 3-7).
Input devices such as switches and sensors can be connected.
Protective ground (

Functional ground (
electrical shock is a problem, connect to the protective ground terminal
and ground both with a ground of 100Ω or less.
CP-series Expansion I/O Units or Expansion Units such as Analogue
I/O Units, and Temperature Sensors can be connected.
Refer to 5-2-4 Connecting Expansion I/O Units and Expansion
Units.
Output status is displayed. An indicator will be ON when the output is
ON.
This is the terminal block for outputs such as relay outputs, transistor
outputs, and the external power supply output.
Loads such as lamps, contactors, and solenoid valves can be con-
nected.
The external supply terminals output up to 300 mA max at 24 VDC.
They can be used as a service power supply for input devices.
A Battery can be installed by opening the cover. (Battery is optional).
