CONTROL OUTPUT
The Controller has four control outputs (control output 1 through 4) which are assigned to control output, alarm output and
other outputs.
Basic output channel configuration is determined by the model number suffix codes as shown below.
Control output 1, Control output 2
R3-TC2Ax
0 − 20mA DC output
R3-TC2Vx
0 − 10V DC output
R3-TC2Px
12V pulse output
Control output 3, Control output 4
Open collector output
Each output channel can be assigned with alarm output (ON/OFF) or with control output (continuous value) as explained in
the table below.
OUTPUT
ON/OFF
CONTINUOUS VALUE
0 − 20mA DC
ON at 100% scaled current; OFF at 0%
scaled current
Scaled output range is converted into a
proportional current range
0 − 10V DC
ON at 100% scaled voltage; OFF at 0%
scaled voltage
Scaled output range is converted into a
proportional voltage range
12V pulse
ON at 12V; OFF at 0V
Scaled output range is converted into a
proportional duty ratio output
Open collector
ON at closed state; OFF at open state
Scaled output range is converted into a
proportional duty ratio output
