Allen-Bradley 1769-IQ32T Discrete Input Module Overview

The Allen-Bradley 1769-IQ32T is a high-density discrete input module. Specifically, it belongs to the Compact I/O family from Rockwell Automation. Therefore, this module provides 32 channels of 24V DC input. Consequently, users select the 1769-IQ32T for applications with many field devices. Moreover, the module works with both MicroLogix 1500 and CompactLogix controllers. Finally, it mounts on a DIN rail or directly on a panel.

Technical Specifications of 1769-IQ32T

The Allen-Bradley 1769-IQ32T has 32 digital input channels. Specifically, these inputs divide into 4 groups with 8 inputs each. The voltage category is 24V DC with sink or source configuration. Nominal voltage rating is 24 Volts DC. Operating voltage ranges from 10 to 30V DC at 30°C. At 60°C, the range is 10 to 26.4V DC. On-state voltage minimum is 10V DC. Off-state voltage maximum is 5V DC.

Input delay for On state is 8 milliseconds. The module uses a prefabricated 32-point communication cable. A 40-pin female connector (1746-N3) ships with the module. This connector prevents front panel wire clutter. The module also works with Allen-Bradley 1492 wiring systems. Replacement terminal block is 1769-RTBN18.

The 1769-IQ32T has a power supply distance rating of 8 modules. Install this module within 8 slots of the power supply. Weight is 0.97 lb or 440 grams. Power supply options include 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. Wire type requires copper rated for 90°C. Solid wire size ranges from 22 to 14 AWG.

Operating temperature ranges from 0°C to 60°C (32°F to 140°F). Vibration rating is 5g at 10 to 500 Hz. Shock rating is 30g for panel mounting. For DIN rail mounting, shock rating is 20g. The module uses tongue-and-groove slots for secure installation. Move the bus lever to the left until it clicks. This ensures proper electrical connection to the controller.

Installation Guidelines for Allen-Bradley 1769-IQ32T

First, mount the 1769-IQ32T on a well-grounded surface. Then, align the tongue-and-groove slots with adjacent modules. After that, push the modules together until they seat fully. Next, move the bus lever to the leftmost position until it clicks. Subsequently, connect the 40-pin female connector to the front panel. Finally, secure the connector with the locking mechanism.

First, shut off all power before wiring the module. Then, strip 8 mm of insulation from each wire. After that, insert each wire into the correct terminal on the 40-pin connector. For sinking inputs, connect DC common to the DC COM terminal. For sourcing inputs, connect V+ to the DC COM terminal. Do not exceed the 30V DC maximum input voltage. Finally, verify the module is within 8 slots of the power supply.

Frequently Asked Questions about 1769-IQ32T

1. What controllers work with the 1769-IQ32T module?

The Allen-Bradley 1769-IQ32T works with MicroLogix 1500 controllers. Specifically, it also works with 1769 CompactLogix systems. Therefore, check your controller model before ordering. The module mounts beside the processor or adjacent modules.

2. What is the power supply distance rating for 1769-IQ32T?

The 1769-IQ32T has a power supply distance rating of 8 modules. Specifically, install this module within eight slots of the power supply. Therefore, maintain proper spacing for reliable operation. Exceeding this distance may cause voltage drop issues.

3. Can I use sink and source wiring on the same module?

Yes, the Allen-Bradley 1769-IQ32T supports sink or source per group. Specifically, each of the 4 groups can be configured independently. Therefore, group one can be sinking while group two is sourcing. Connect the DC COM terminal according to your wiring method.

4. What is the 1746-N3 accessory shipped with this module?

The 1769-IQ32T includes a 1746-N3 40-pin female connector. Specifically, this connector mounts directly to the module front panel. Therefore, it accommodates all 32 input channels in one compact assembly. This design leaves room for troubleshooting and future modifications.

5. What is the input delay time on the 1769-IQ32T?

The Allen-Bradley 1769-IQ32T has an On delay of 8 milliseconds. Specifically, this is the time from input signal application to logic recognition. Therefore, account for this delay in your control program timing. Off delay uses the same 8 ms specification.
