750-484 / 040-000, 2-channel analogue input 4 20 mA HART Extreme blue

2-channel analog input 4 20 mA HART Extreme blue

2-channel analog input, 4... 20 mA HART, self-safe, ExtremeThe analog input module is used to connect two measuring formats in the field with HART interface, which are used in the potentially explosive area of zone 0 + 1. It supplies the measuring converters, records the process value over the analog interface and allows the setting up of a HART communication to parametrize or The installation of the WAGO I / O system 750 XTR has to be carried out either in zone 2 or in the non-explosion-prone area. The supply voltage of 24 V is fed into the field by the power contacts via pre-resistors (HART +). The screen connection is direct to the support rail. The measuring input is equipped with a current limit that limits the current to a maximum of 25 mA. This module provides the power supply for 2-conductor transmitter, which does not have its own power supply. It can use up to 4 HART side variables (PV, SV, TV, QV) per channel in the cyclic process image of the coupler or (parametrierable). For the HART communication to connected intelligent HART field devices, the HART protocol can be in the cyclic process image of the coupler or (parametrierable). For some (programmable) couplers, FDT- / DTM devices are available, with which HART- toolrouting is possible for the connected HART- device. The device is suitable for use under difficult environmental conditions: greatly extended temperature range higher voltage strength and EMC resistance higher vibration and shock resistance
