A-B 1756-IF8

Description

A-B 1756-IF8 is an analog input module of the Rockwell Automation(Allen-Bradley)ControlLogix product series.The following is a detailed introduction to the module:

1.Module Overview

Brand and Series:A-B(Allen-Bradley),ControlLogix Series.

Function:This module is used to convert external analog signals(such as voltage and current signals)into digital signals that can be read by PLC(Programmable Logic Controller)to monitor and control the status of equipment or process parameters.

2.Technical Specifications

Number of Channels:It has 8 single-ended differential input channels and 2 high-speed differential input channels(but it is usually described as 8-channel single-ended or 4-channel differential,because only one of every four channels can be used in the high-speed differential wiring mode).

Input Signal Type:It can be configured as+/-10VDC,0-10VDC,0-5VDC voltage signals and 0-20mA current signals.

A-B 1756-IF8

Resolution:The resolution of+/-10VDC is 15 bits,and the resolution of other signal types is 16 bits.

Input range:Voltage signal range is-10V to+10V(or 0-10VDC,0-5VDC according to configuration),current signal range is 0 to 20mA.

Backplane voltage and current ratings:5.1V DC(maximum 150mA)and 24V DC(maximum 40mA).

Power consumption:1.73 watts.

Maximum overvoltage protection:30V DC(voltage)and 8V DC(current).

3.Wiring and configuration

Wiring mode:supports single-ended wiring,differential wiring,and high-speed mode differential wiring.

Single-ended wiring:All input devices are connected to a common ground,allowing one side of the signal input to be compared with the signal ground.

Differential wiring:used to improve noise immunity,used when separate signal pairs or common ground are not available.

High-speed mode differential wiring:used in situations where data updates are required as quickly as possible,but this mode only allows one of every four channels on the module to be used.

Removable terminal block:requires a removable terminal block(RTB)such as 1756-TBCH or 1756-TBS6H.

Fourth,Functions and Features

Module filter:used to eliminate noise and interference in the input signal.

Underrange/overrange detection:can detect whether the input signal exceeds the configured input range.

Process alarm and disconnection detection:when the input signal is abnormal or disconnected,an alarm signal can be issued.

Multiple input ranges:each channel can be configured with different input ranges as needed.

Real-time sampling:can collect data of input signals in real time.

Digital filter:further process the input signal to improve the accuracy of the data.

Rate alarm:when the rate of change of the input signal exceeds the set range,an alarm signal can be issued.

5,Installation and Application

Installation location:can be installed in the local chassis along the controller or in the distributed I/O rack.

Communication interface:communicate with the PLC through the backplane bus to transmit input signals and receive control instructions.

Application range:suitable for various industrial automation systems,such as transmitters,sensors,signal separators,signal isolators,panel meters and other equipment signal acquisition and processing.
