HART support
Native compatible with HART 5 smart transmitter, capable of reading instrument range, diagnosis, and secondary variables through a handheld device
Protection and isolation
short circuit protection
Each channel is equipped with a built-in PTC thermistor, which can withstand up to 30VDC input errors without burning out the module; Channel to ground/24V short circuit automatic current limiting protection
isolation level
On site signal side ↔ Backplane bus: group isolation, withstand voltage 500V AC
Circuit diagnosis
Automatically detect 4-20mA circuit disconnection and over range, upload the fault to the controller and light up the channel indicator light
