3.1 Control Example
This chapter describes the following control example to facilitate under-
standing of the basic operation of the E5CK controller.
This description assumes that the controller is operated under the follow-
ing conditions.
•
A humidity sensor of output 4 to 20 mA is connected to the controller.
The measuring range of the humidity sensor is set to 10 to 95%.
•
A humidifier is controlled by pulse output to maintain humidity at a
constant 60%.
•
An alarm is output when the humidity exceeds the upper limit value
(70%) or lower limit value (50%).
•
Output unit: relay/relay type (E53-R4R4)
•
Input type jumper connector: “I (current input)”
