Overview

Essential details：1756-L72K ControlLogix Controllers Allen Bradley

Products Description

The ControlLogix® controller provides a scalable controller solution that is capable of addressing many I/O points. You can place the ControlLogix controller into any slot of a ControlLogix I/O chassis, and install multiple controllers in the same chassis.
ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over network links. The ControlLogix 5580 controllers have an embedded Ethernet port for a direct connection to Ethernet-enabled devices and networks, and also support communication interface modules in the local chassis. To provide communication for
ControlLogix 5570 or ControlLogix 5560 controllers, install the appropriate communication interface module into the local chassis. ControlLogix 5580 and ControlLogix 5570 controllers are available with a conformal coating. A conformal coating provides a layer of protection against contaminants and humidity to help protect the assembly and extend product life in harsh, corrosive environments. Products with a conformal coating have a ‘K’ suffix at the end of the catalog number.

1756-L72

The 1756-IF16H has an integrated Analog to Digital Converter (ADC) using successive approximation method. Analog conversion resolution range is 16-21 bits, allowing more measuring points to be displayed. Converted signal is saved in Integer mode (left justified, 2 s complement) IEEE 32-bit floating point number.

Allen-Bradley recommends use of Single wire connection when terminating signals to the 1756-IF16H. Wire diameter is 0.33…2.1 mm2 (22…14 AWG) solid or stranded shielded copper wire with insulation rating of 105 °C (221 °F) or higher and maximum insulation thickness of 1.2 mm (3/64 in.). Compatible Removable Terminal Block (RTB) for use with the 1756-IF16H are 1756-TBCH and 1756-TBS6H.

The 1756-IF16H has a calibrated accuracy which is better than 0.13% of range on all filters while the module error is 0.3% of range. The module’s input scan time is 11…328 ms that is filter dependent while the module HART scan time is estimated at 1 s if all channels are HART enabled.
