2-2-5 E5EC-B Terminal Block Wiring Example
Terminal Arrangement
The terminals block is divided into five types of terminals: control output 1, sensor input, auxiliary outputs, input
power supply, and options.
Note: The terminals that are shaded gray are not used.
Precautions for Correct Use
When you purchase the Digital Controller, it will be set for a K thermocouple (input type = 5). If a
different sensor is used, an input error (s.err) will occur. Check the setting of the Input Type
parameter.
Model Numbers
The specification for control output 1 is given in the following location in the model number.
