Wago 750-482 WAGO I/O-SYSTEM 750 Analog Input Module
2-Channel Analog-Input HART-Communication, Signal: DC 4-20 mA, Sensor connection: 2x (2-conductor), Signal characteristic: Single-Ended, Resolution: 12 Bit, Conversion time: 10 ms, Input filter parametrizable, Diagnostics: Wire break/Measurement range overflow
The analog input module powers the transducers, receives transmitted analog signals, and with electrical isolation, transmits the signals to the fieldbus.
The 24V supply for the field is derived from the module's power jumper contacts. The shield (screen) is directly connected to the DIN rail. At approx. 25mA, the overload protection switches the measurement input to a high-resistance state. Under normal operating conditions it will automatically switch back. This input module can supply the voltage for 2-wire transducers.
Up to 4 HART dynamic variables (PV, SV, TV, QV) per channel can be mapped in the cyclic process image of the coupler or controller (configurable). For HART communication with connected intelligent HART field devices, the HART protocol can be mapped in the cyclic process image of the coupler or controller (configurable).
FDT/DTM device drivers are available for select (programmable) couplers, allowing HART tool routing to the connected HART device.
