Input System
Main Setting Input
The main setting can be selected from the following five input systems.
Automatic Input
■
Analog input (4 to 20 mA or 1 to 5 V)
Used to connect to outputs such as the linear output from a Temperature Con-
troller.
■
Communications (RS-485)
Used to connect with a device that uses the CompoWay/F protocol such as for
the EJ1 Modular Temperature Controller.
■
Voltage ON/OFF input (0 or 5 VDC)
Used to connect to outputs such as a time-proportional control output from a
temperature controller. (Only for commands for switching outputs ON and
OFF with 5 V or 0 V. The input value is set manually.)
Manual Input
■
External Variable Resistor Main Setting
Use an external G32X-V2K Variable Resistor to set the input value.
■
Key Input Main Setting
Use the keys on the front of the G3PW Power Controller to directly set the
input value.
Relationship between Input Signal and Input Value
There is a linear relationship (i.e., a proportional relationship) between an
analog input signal and the input value.
