A-B  1756-IF8  ControlLogix 8 Point A/I Module

Allen Bradley 1756-IF8 is an analog input module of the ControlLogix Programmable Automation Controller (PAC) series. This analog input module has eight (8) input channels that can be configured for various input signals, such as+/-10VDC, 0-10VDC, 0-5VDC voltage signals, and 0-20 mA current signals. This module is typically used to connect analog signal generation instruments and equipment, such as transmitters, sensors, signal splitters, signal isolators, panel instruments, and other similar devices.
1756-IF8 is a single slot module with high conversion resolution. Its resolution ranges from 15 bits to 16 bits. The specific module resolution is 10.25V: for+/-10VDC, 320V/count (15 bit plus polarity), 160V/count (16 bit); For 0-10VDC, 80/V count (16 bits); For 0-5VDC and 0... 20.5mA: For 0-20mA signals, each count (16 bits) is 0.32 A.
There is actually no limit to the number of installation instances for this module. Most ControlLogix controllers are capable of processing up to 4000 analog I/O signals. The 1756-IF8 can be installed in the local chassis along the controller or in a distributed I/O rack.
1756-IF8 uses the Sigma Delta conversion method and stores the received signal in integer mode (left aligned, 2-s complement) IEEE 32-bit floating-point registers. It uses 1756-TBCH and 1756-TBSH movable terminal blocks (RTBs) with user-defined mechanical keying.
