Feimu Technology offers you this Allen Bradley 1762-IF4. It is not responsible for monitoring the on-off status of switches, but is specifically designed to read those continuous changing signals, such as the values transmitted by pressure transmitters or the readings displayed by temperature gauges. If your equipment needs to know the current pressure or temperature, then it cannot do without it. We have ample stock here precisely to prevent you from having to search the entire world for this small module when expanding the functionality of your equipment.
The Allen-Bradley 1762-IF4 is a compact 4-channel differential analog input module specifically designed for MicroLogix 1100, 1200, and 1400 series programmable logic controllers. It enables the conversion of analog signals from field sensors and transmitters into digital signals, offering 16-bit resolution and high accuracy. It can be independently configured as current or voltage input mode via DIP switches and supports flexible wiring for 2-wire, 3-wire, or 4-wire transmitters. It is installed using DIN rail or panel mounting methods, communicates with the controller through a dedicated flat ribbon cable, is easy to integrate and expand, and has a compact size, widely used in industrial applications such as process control, data acquisition, and mechanical equipment condition monitoring.
This Allen Bradley 1762-IF4 can simultaneously receive 4 analog signals, whether they are voltage signals or current signals. It can handle all of them, and through software, you can set whether each group is in voltage mode or current mode, which is much more flexible. Its conversion speed is quite fast, and the accuracy is sufficient. It can fully meet the needs of general industrial measurement. The most crucial point is that it comes with a filtering function. In factories where the electrical environment is noisy, it can help you filter out those chaotic interference waves, ensuring that the pressure or temperature values you read are stable and not fluctuating.
When shipping these precision electronic small modules, the most worrying issue is that the connection posts might get bent or the gold pins might be damaged by static electricity. Feimu Technology has unique experience in this aspect. We will first put a thick anti-static bag over this module, then wrap it in bubble wrap, and finally put it in a thick cardboard box. In the box, we will fill it with padding to ensure that it doesn't even shake. No matter whether you deliver it to the Americas or Europe, after this rough journey, our packaging can guarantee that it remains intact. When you open it, the connection terminals will still be straight and can be immediately installed on the machine.
The Allen Bradley 1762-IF4 is a 4-channel analog input module for the MicroLogix 1100, 1200, and 1400 series. It converts analog signals from field sensors and transmitters into digital values for the PLC.

The 1762-IF4 supports both voltage and current inputs. Each channel can be configured independently via DIP switches on the module.
| Input Mode | DIP Switch Setting | Input Range | Typical Application |
|---|---|---|---|
| Voltage | Switch ON | 0-10V or ±10V | Pressure transmitters, position sensors |
| Current | Switch OFF | 0-20mA or 4-20mA | Temperature transmitters, flow meters |
How to configure:
Transmitter wiring:
The 1762-IF4 has two variants. One is non-isolated (1762-IF4). The other is isolated (1762-IF4I). This comparison helps you select the correct model for your application.
| Feature | 1762-IF4 (Non-isolated) | 1762-IF4I (Isolated) |
|---|---|---|
| Channel isolation | No isolation between channels | Isolation between channels and logic ground |
| Common mode voltage | Limited to ±10V | Up to ±400V |
| Noise immunity | Good for standard applications | Better for high-noise environments |
| Ground loop issues | Potential problem with multiple grounds | Isolation eliminates ground loops |
| Price | Lower cost | Higher cost |
| Best for | Standard industrial environments | Noisy environments, remote sensors, different ground potentials |
When to use each:
The 1762-IF4 returns raw digital counts to the PLC. These counts must be scaled to engineering units (such as PSI, °C, or mA) in the PLC program.
Raw count ranges:
Scaling example (4-20mA to PSI):
The 1762-IF4 has LED indicators on the front panel. These provide immediate status information without a programming terminal.
| LED | Status | Meaning | Action |
|---|---|---|---|
| PWR | Green | Module powered and operating normally. | No action needed. |
| PWR | Off | No power to module. | Check MicroLogix power. Check expansion cable connection. |
| CH0 - CH3 | Green | Channel configured and reading normal. | No action needed. |
| CH0 - CH3 | Off | Channel not configured or not used. | Configure channel in RSLogix 500. |
| CH0 - CH3 | Flashing | Input signal out of range. | Check sensor wiring. Check sensor range. |
Allen Bradley 1762-IF4 modules are commonly counterfeited. Use these checks to verify authenticity.
If the module shows incorrect readings or the LEDs behave abnormally, suspect a counterfeit. Contact Feimu Technology with photos for verification.
This module is a non-isolated type, with lower cost and suitable for large non-high-voltage interference environments. While 1762-IF4I provides electrical isolation between channels and between channels and the logic ground, offering stronger anti-interference capability, it is suitable for situations with complex signal grounding or high common-mode voltages, and usually has a higher price.
It is still a standard configuration and there is no direct discontinued substitute. You can only purchase the original or disassembled parts.
The packaging usually does not include extension cables for connecting to the PLC. You need to purchase the cables separately based on the number of expansion slots.
It is usually compliant with standards such as cULus (North American certification), CE (European conformity).
