Product Overview of the Allen-Bradley 1769-IQ16

The Allen-Bradley 1769-IQ16 is a reliable discrete input module. It belongs to the 1769 Compact I/O product family. This module provides sixteen (16) DC input channels. These channels operate at a 24VDC voltage category. The 1769-IQ16 supports both sink and source wiring configurations. Users can integrate it seamlessly with CompactLogix controllers. It also works perfectly with the MicroLogix 1500 system. This module saves space while delivering high-density input capacity.

Technical Specifications

Input and Electrical Ratings

The 1769-IQ16 has sixteen (16) digital input points. These points divide into two (2) isolated groups. Each group contains eight (8) input channels. The operating voltage ranges from 10 to 30V DC at 30 °C (86 °F). At 60 °C (140 °F), the range is 10 to 26.4V DC. The off-state voltage measures 5V DC maximum. The on-state voltage requires 10V DC minimum. Input delay time for both ON and OFF is 8 ms. Nominal input impedance is 3 kΩ. Maximum surge current reaches 250 mA. The 1769-IQ16 draws 115 mA current at 5.1V DC. Heat dissipation reaches a maximum of 3.55 W (12.11 BTU/hour).

Isolation and Environmental Data

This module provides reinforced insulation per IEC Class 2. Isolation voltage is 75V DC between inputs and bus. Group-to-group isolation tests at 1697V DC for 1 second. The 1769-IQ16 measures 118 x 35 x 87 mm (4.65 x 1.38 x 3.43 in.). It weighs approximately 0.27 kg (0.60 lbs). Operating temperature ranges from 0 °C to 60 °C (32 °F to 140 °F). Relative humidity tolerance is 5% to 95% without condensation. It uses an open-style enclosure. The power supply distance rating is 8 modules.

Wiring and Compatibility

Use 22 to 14 AWG solid copper wire for installation. For stranded wire, use 22 to 16 AWG. Wire type must be Cu-90 °C (194 °F). The replacement terminal block is 1769-RTBN18. Compatible power supplies include 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. The 1769-IQ16 fits in any 1769 CompactLogix chassis slot. It also mounts directly after a MicroLogix 1500 base unit. You can place it in local or remote I/O banks. Just observe the 8-module power supply distance rating.

Installation Guidelines

Mount the 1769-IQ16 on a standard DIN rail or a flat panel. Use the upper and lower mounting tabs for panel installation. For DIN rail mounting, pull the latches outward first. Press the module firmly onto the rail. Push the latches back inward to lock the 1769-IQ16 in place. Align the bus lever with the adjacent module. Turn off all power before wiring the terminal block. Terminal screw torque is 0.68 N-m (6 lb-in). This module occupies a single slot in the chassis.
