Allen Bradley 1756-IF8H ControlLogix Analog Differential Input HART 8-Points

Description

TheAllen-Bradley 1756-IF8H is a HART Analog Modulebelongs to theControlLogixsystem. It requires a 36-position spring clamp RTB, or removable terminal block housing, and it can either be the 1756-TBCH or 1756-TBS6H and iscompatible with the HART 5, 6, and 7.8 differential voltage or current inputs are availablefor this module, withone HART modem per module. This 1756-IF8H input module receives signals from process value transmitters and then converts them to the corresponding measurement values for use in the Logix controller. The 1756-IF8Hhas three data formatsfor you to choose from using the Studio 5000 Logix Designer: analog only, analog and HART PV, and analog and HART by channel. If you want the members of the tag to be arranged like those of non-HART analog input modules, you should choose the analog and HART PV format. Analog values are grouped together near the end of the tag, making it easier to view all 8 analog values at the same time. But if you want the Status, Analog Value, and Device Status for every channel to be grouped together in a tag, you should choose the analog and HART by channel format. This will make it easier for you to view all data related to a field device.

Using this module will let you have ananalog and HART connectivity in one module.HART commands can be transmitted as unscheduled messageswith the 1756-IF8H. It alsosupports asset management softwareto the HART device and there areno external hardware requirementsneeded for accessing the HART signal.Other featuresof the 1756-IF8H include multiple current and voltage input ranges, real-time sampling, process alarms, wire-off detection, module filter, under-range and over-range detection, rate alarm, and highway addressable remote transducer (HART) communication. The 1756-IF8Hhas variable operational ranges for every channelin the module. Possible ranges for you to choose from include -10 to 10 Volts, 0 to 5 Volts, 0 to 10 Volts, 0 to 20 milliamps, and 4 to 20 milliamps, with HART instruments using the latter range. The resolution of this module ranges from 16 to 21 bits. Backplane voltage and current ratings are 5.1 Volts DC, 300 milliamps, 24 Volts DC, and 135 milliamps and its total backplane power is 4.77 Watts. Voltage power dissipation is 3.21 Watts and 4.01 Watts for the current and it also has a maximum overvoltage protection of 30 Volts DC (voltage) and 8 Volts DC (current).
