Allen-Bradley 1762-IF4 Analog Input Module

1762-IF4 4-Channel Analog Input Module

Product Introduction

The Allen-Bradley 1762-IF4 expands your MicroLogix system with four differential analog inputs. This module handles both current and voltage signals. Specifically, it accepts 4-20 mA and -10 to +10V DC inputs.

This analog module works seamlessly with MicroLogix 1100, 1200, and 1400 controllers. It connects via a simple ribbon cable to the controller bus. Moreover, the 1762-IF4 uses a Delta-Sigma converter for accurate data acquisition. It provides 15-bit resolution for precise measurements.

Furthermore, this module offers flexible mounting options. You can install it on a DIN rail or directly on a panel. Its compact dimensions save valuable space in your control cabinet.

Technical Specifications

The 1762-IF4 delivers reliable analog input performance. It features four differential input channels that accept both positive and negative signal polarities. Each channel is independently configurable for current or voltage signals.

Here are the key signal ranges:

• Voltage Normal Range: -10.5V to +10.5V DC (accepts positive and negative voltages)

• Current Normal Range: 4 to 20 mA

• Current Full Range: -21 mA to +21 mA (accepts bidirectional current)

Additionally, this module provides a repeatability of ±0.12%. Its Delta-Sigma converter ensures stable and accurate readings. The 1762-IF4 also includes an IP20 enclosure rating for basic protection.

Compatibility and System Expansion

This analog module integrates easily with several MicroLogix platforms. For instance, the MicroLogix 1100 supports up to 4 expansion modules. Meanwhile, the MicroLogix 1200 accommodates up to 6 modules. The MicroLogix 1400 can handle up to 7 expansion modules.

Connecting the 1762-IF4 is straightforward. Use the provided flat ribbon cable to attach it to the controller bus. This cable connects via pin contacts on the front panel. Additionally, you can mix this module with other I/O types.

Installation and Wiring Guidelines

Mount the 1762-IF4 using either DIN rail or panel mounting. Its dimensions are 90mm (H) x 87mm (D) x 40mm (W). Including mounting tabs, the height is 110mm.

For wiring, use shielded cable such as Belden 8761. This reduces electrical noise and ensures signal integrity. The module includes a finger-safe cover on the terminal blocks. This protects users during wiring.

Also, configure the input type using the DIP switches on the module. You can select current or voltage per channel. The 1762-IF4 supports 2-wire, 3-wire, and 4-wire transmitters. This flexibility adapts to various field devices.

Data Format and Processing

The 1762-IF4 converts analog signals into digital data. It uses an Analog-to-Digital (ADC) converter for this task. The resulting data is stored in the analog input register.

You can format this data as Raw/Proportional or Scale for PID. This allows direct use in control loops. Additionally, the module features a field-upgradable flash OS. This lets you update firmware without changing hardware.
