TO Option
The TO (Temperature Output) option includes an additional independent 4-20mA output for temperature
measurement. The temperature range is from -40°C to 125°C with an overall accuracy of ±5%FSO. The
imbedded temperature sensor monitors the environment internal to the sensor housing and is situated at
approximately mid level.

Note:
- The same power supply can be used for both 4-20mA loops. Connect both positive terminals directly to the
power supply, then use the negative terminals for independent process loops.
