Analog Input Units Section 7-2
■ Input Terminal Arrangement
Note When using current inputs, voltage input terminals must be short-circuited
with current input terminals.
2. Expansion I/O Connecting Cable
Connected to the CPU Unit or Expansion Unit expansion connector. The
cable is attached to the Analog Input Unit and cannot be removed.
Note Do not touch the cables during operation. Static electricity may cause operat-
ing errors.
3. Expansion Connector
Connected to the next Expansion Unit or Expansion I/O Unit to enable ex-
pansion.
Main Analog Input
Unit Specifications
A maximum of seven Units can be connected, including other Expansion
