Product Details
4-channel analog input acquisition moduleDerived from independent functional modules, please refer to:
PD3060-PT100 temperature acquisition module, PD3058 analog acquisition module, IOMxxxx IO module.
4-channel analog input acquisition moduleModule interface
A: RS485 serial communication A
B: RS485 serial communication B
Power supply V+: Positive pole of DC power supply
Power GND: DC power supply negative terminal, common terminal
IN (x): Analog input terminal
DO (x): Switching output terminal
Three wire connection method:
RTD (n)+: Sensor power supply terminal, approximately 0.5mA output.
RTD (n) -: Sensor measurement input.
GND: Sensor common terminal.
Two wire connection method:
RTD (n)+: Sensor power supply terminal+measurement input terminal, approximately 0.5mA output.
RTD (n) - needs to be short circuited to GND.
GND: The other end of the sensor
Bit operation function code: 01H (read multiple output switch status), 02H (read multiple input switch status)
05H (set single switch output status), 0FH (set multiple switch output status)
The bit operation function code is the same as the IOMxxxx IO module. Please refer to the "IOMxxxx IO Module Manual".
