I/O系統(tǒng): 2-通道模擬量輸入 (750-484/040-000)
This analog input module connects two field-side signal conditioners equipped with a HART interface that are to be used in hazardous areas of Zone 0+1.
The module supplies signal conditioners, reads process values via analog interface, and enables HART communication for configuring and importing dynamic variables.
The WAGO I/O System 750 XTR must be installed either in Zone 2 or in a non-hazardous area.
The 24 V supply is supplied to the field contacts (HART +) from the power jumper contacts via multipliers. The shield directly connects to the DIN-rail.
The measurement input is equipped with current limitation, which limits the current to 25 mA. This module powers 2-wire signal conditioners without dedicated power supply.
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 (parameterizable). 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 (parameterizable).
FDT/DTM device drivers are available for select (programmable) couplers, allowing HART tool routing to the connected HART device.
The device is ideal for operation in extreme environments thanks to:
