DPT-IO-MOD
Differential pressure transmitter with Modbus communication and Input terminal
The DPT-IO-MOD differential pressure transmitter for air conforms to Modbus over serial line protocol using RTU transmission mode and RS485 interface. The digital output signal is sent over Modbus enabling the DPT-IO-MOD to connect directly to a field communications network.
Communication: RS-485 Modbus (RTU)
Accuracy :
Pressure < 125 Pa = 1 % + ±2 Pa
pressure > 125 Pa = 1 % + ±1 Pa
Zero point calibration: via Modbus or by pushbutton
Measuring units: Pa, kPa, mbar, inchWC, mmWC, psi
Supply voltage: 24 VDC ±10 % / 24 VAC ±10 %
Response time: 1...20 s selectable via menu
Protection standard: IP54
