Allen-Bradley 1771-IFE PLC-5 Analog Input Module

Technical Specifications

The 1771-IFE delivers reliable analog signal processing with the following specifications:

Engineering Advantages

High-Resolution Signal Acquisition
The module utilizes 12-bit resolution to digitize analog signals. This granularity ensures that the control system receives accurate data, minimizing quantization errors in critical control loops.

Versatile Input Configuration
You can configure the 1771-IFE to accept 16 single-ended inputs or 8 differential inputs. This flexibility allows you to adapt the module to various sensor types without changing hardware.

Efficient Data Transfer
The Block Transfer interface manages data exchange between the module and the PLC-5 processor. This method optimizes scan times and ensures that analog data updates synchronously with the control logic.

Installation and Wiring
Install the module directly into the 1771 I/O chassis. It draws 750 mA from the backplane, so verify your power supply budget before adding additional cards. Use shielded twisted-pair cables for all analog connections to reject electromagnetic interference (EMI) common in industrial environments.

FAQs

Q: What is the difference between single-ended and differential inputs on this module?
A: Single-ended inputs share a common ground reference, allowing for 16 channels. Differential inputs isolate each signal pair, reducing noise susceptibility but limiting the module to 8 channels.

Q: Does the 1771-IFE support both voltage and current inputs?
A: Yes, the module accepts both voltage and current signals. You typically configure the input type via the external terminal block wiring or internal jumpers, depending on the specific revision.

Q: Is this product new?
A: Yes, we supply 100% Brand New and genuine Allen-Bradley 1771-IFE modules.
