The PTL517 digital pressure transmitter can display all four digit values based on the 4-20mA signal output by the transmitter, which is stable and reliable. The alarm type has two alarm outputs. When an alarm is triggered, the corresponding alarm light on the meter panel will flash. There are three types of alarm type meters, which are optocoupler output type. The external power supply can output a current of 20mA and directly drive a relay with a maximum of 16A. Relay output type, built-in relay, contacts can directly drive the actuator through 1A current nearby. Transistor output type, capable of outputting a current of 300mA.
