Allen-Bradley 1762-IF4 Analog Input Module – MicroLogix 1100/1200/1400 Expansion Series
When a MicroLogix controller loses its analog input capability, the consequences ripple immediately through the production floor: process variables go blind, PID loops open, and operators are left managing critical equipment by guesswork. Temperature drifts unchecked, flow rates exceed safe limits, and batch quality collapses — all because four analog channels went dark. The Allen-Bradley 1762-IF4 exists precisely to prevent this scenario, delivering reliable, high-resolution analog signal acquisition that keeps your control loop closed and your process in spec.
Within the MicroLogix 1762 I/O expansion family, the 1762-IF4 occupies the role of the workhorse analog front-end: four independently configurable current/voltage input channels that integrate directly into the MicroLogix 1100, 1200, and 1400 backplane without additional gateways or signal converters. Globally, this module has been deployed across tens of thousands of OEM machines and retrofit projects, making it one of the most field-proven analog expansion modules in the Rockwell Automation portfolio.

Key Features & Benefits
- 4 Independent Differential Analog Inputs — each channel configurable for voltage or current, eliminating the need for external signal conditioners in mixed-signal environments.
- 12-Bit Resolution — provides 4096 discrete levels per channel, sufficient for precise PID control, flow measurement, and temperature monitoring in most industrial processes.
- Software-Selectable Input Ranges — switch between 0–10 V, ±10 V, 0–20 mA, and 4–20 mA via RSLogix 500/Micro without hardware jumpers, reducing commissioning time.
- Direct Backplane Integration — snaps onto the MicroLogix 1762 expansion bus; no additional power supply or communication wiring required.
- Compact DIN-Rail Form Factor — 40 mm wide module fits into tight panel layouts alongside other 1762 I/O modules.
- Open-Circuit & Over-Range Detection — module flags out-of-range or broken-wire conditions in the input data file, enabling fault-tolerant ladder logic.
- RoHS Compliant — meets environmental directives for global export and installation.
Industry & Equipment Applications
- Food & Beverage: Temperature and pressure monitoring in pasteurization, mixing, and filling lines.
- Water & Wastewater: Flow transmitter and level sensor inputs for pump station control.

Frequently Asked Questions
Q: Is the 1762-IF4 compatible with MicroLogix 1000?
A: No. The 1762-IF4 uses the 1762 expansion bus, which is only supported by MicroLogix 1100, 1200, and 1400 controllers. MicroLogix 1000 does not support 1762 expansion I/O.
Q: Can I mix voltage and current inputs on the same module?
A: Yes. Each of the four channels is independently configurable for voltage (0–10 V or ±10 V) or current (0–20 mA or 4–20 mA) via the RSLogix 500 channel configuration dialog.
Q: How many 1762-IF4 modules can I connect to one MicroLogix controller?
A: The maximum number of 1762 expansion modules per controller depends on the CPU model and total I/O point budget. MicroLogix 1400 supports up to 7 expansion modules. Consult publication 1762-UM001 for exact limits.
Q: Do you supply the module with a warranty?
A: New factory-sealed units carry the original manufacturer warranty. Surplus units are sold with Konmask.com’s 90-day inspection guarantee. Contact us for details.
Q: What programming software is required?
A: RSLogix 500 (version 7.0 or later) or RSLogix Micro is required to configure the 1762-IF4 channel parameters and map data to the controller’s input file.
Q: Can you provide an export certificate of origin?
A: Yes. We provide a Certificate of Origin (COO) for all international shipments upon request.
