Chapter 2. OUTLINE OF FUNCTIONS
2 - 1 Input/Output Configuration
2-1
● PV input
Sensor or range is selected for the PV input. The selection range may vary
depending on the input type of the model (T: Thermocouple, R: RTD, L: DC
current, DC voltage).
● Control output
When the control output type of the model is “R: Relay” or “V: Voltage pulse”,
the control output becomes the ON-OFF control output or time proportional
output. When the time proportional output is used, the time proportioning cycle
time can be set. When the control output type of the model is “C: Current”, the
control output becomes the continuous output (analog output). When the model
has two control outputs, the heat/cool control can be used only with "Simple
configuration".
● Event output
When the model provides the event, the alarm or control mode set in [Event type]
can be output as DO (digital output).
● DI (digital input)
When the model provides the DI, the function set with the DI assignments can be
selected.
● CT (current transformer) input
When the model provides the CT input, the heater burnout alarm can be output
from the event output.
