Technical characteristics of Universal Transmitter PR 4116
- When PR4116 Universal Transmitter / Temperature Transmitter is used in combination with the PR 4500 display series, all operational parameters can be modified to suit any application. As the PR4116 transmitter is designed with electronic hardware switches, it is not necessary to open the device for setting of DIP-switches.
- A green / red front LED indicates normal operation and malfunction. A yellow LED is ON for each active output relay.
- Continuous check of vital stored data for safety reasons.
- 4-port 2.3 kVAC galvanic isolation.
Mounting / installation / programming
- Very low power consumption means units can be mounted side by side without an air gap – even at 60°C ambient temperature.
- Configuration, monitoring, 2-point process calibration and more are accomplished using PR’s 4500 series of detachable displays.
- All programming can be password-protected for PR 4116 Universal Transmitter / Temperature Transmitter.
