E5@C Digital Temperature Controllers User’s Manual (H174)
Terminal Arrangement
The terminals block is divided into five types of terminals: control outputs 1 and 2, sensor input, auxiliary
outputs, input power supply, and options.
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 specifications for control outputs 1 and 2 are given in the following location in the model number.
