Allen-Bradley High Speed DC Input Module for CompactLogix Systems

Overview of the Allen-Bradley 1769-IQ16F Module

For high-speed digital input applications, the Allen-Bradley 1769-IQ16F provides a versatile 16-point DC input module.
This CompactLogix series module operates on 24 Volts DC with sink or source input wiring options.
Specifically, the 1769-IQ16F supports high-speed operation for demanding automation tasks.
In addition, the module features configurable digital filter times from 0 to 2 milliseconds.
When terminal blocks or doors become damaged, you can replace them easily without replacing the whole module.
Furthermore, the 1769-IQ16F carries current product status from Rockwell Automation.
Accordingly, this input module suits applications requiring fast and reliable digital signal detection.

Technical Specifications of the 1769-IQ16F Module

Below are the complete technical parameters for this high speed DC input module.

Input Configuration and Wiring Options

The 1769-IQ16F features 16 digital inputs arranged as 8 points per group.
Each group can wire inputs as either sink or source depending on your field devices.
For sink wiring, the input common connects to +24V DC and the field device switches to 0V.
For source wiring, the input common connects to 0V and the field device switches to +24V DC.
The Allen-Bradley 1769-IQ16F accepts both wiring methods without configuration changes.
This flexibility reduces spare parts inventory across different machine designs.
Thus, the same module works for both sourcing and sinking field devices.

Operating Voltage and Temperature Derating

The 1769-IQ16F operates reliably across a range of supply voltages.
At 30 degrees Celsius (86 degrees Fahrenheit), the operating voltage spans 10 to 30 Volts DC.
At 60 degrees Celsius (140 degrees Fahrenheit), the range reduces to 10 to 26.4 Volts DC.
This derating ensures reliable operation at elevated cabinet temperatures.
The Allen-Bradley 1769-IQ16F working voltage rating reaches 30 Volts AC and 30 Volts DC.
For DC inputs, stay within the specified range for proper ON/OFF detection.
Thus, consider ambient temperature when designing your control cabinet layout.

Input Characteristics and Thresholds

The 1769-IQ16F defines clear ON and OFF state thresholds for reliable detection.
Maximum OFF state voltage measures 5 Volts DC at 1.5 mA leakage current.
Minimum ON state current requires 2.0 mA at 10 Volts DC input voltage.
Input impedance measures 3 kΩ for consistent current draw across all inputs.
Inrush current reaches 250 mA briefly when inputs first energize.
The Allen-Bradley 1769-IQ16F inputs switch cleanly between ON and OFF states.
Thus, field devices with marginal signal levels must meet these thresholds.

Configurable Digital Filter and Delay Times

The 1769-IQ16F offers configurable digital filter times for noise immunity.
For OFF to ON mode delay, select from 0, 100, 500, 1000, or 2000 microseconds.
Similarly, for ON to OFF mode delay, the same five filter options are available.
Maximum input signal delay (ON to OFF) measures 2 milliseconds at the fastest setting.
Maximum input signal delay (OFF to ON) measures 300 microseconds for high-speed response.
The Allen-Bradley 1769-IQ16F filter rejects electrical noise from contact bounce.
Thus, you can balance speed versus noise immunity for each application.

Current Draw and Power Consumption

The 1769-IQ16F draws 110 mA from the 5.1 Volt DC backplane supply.
This moderate current draw suits most CompactLogix power supply configurations.
Total heat dissipation reaches 3.55 Watts under maximum input load.
For power supply distance rating, the Allen-Bradley 1769-IQ16F supports 8 modules from the supply.
This distance rating follows standard 1769 system power distribution rules.
For proper operation, observe the power supply distance when positioning the module.
Thus, the module integrates easily into standard 1769 I/O systems.

Isolation and Electrical Protection

The 1769-IQ16F provides 75 Volt isolation for electrical safety and noise rejection.
For reinforced insulation, the module meets IEC Class 2 standards for protection.
Testing validates isolation at 1679 Volts DC for 1 second between input point and BUS.
Similarly, testing validates isolation between input groups at the same 1679 Volts DC.
The Allen-Bradley 1769-IQ16F prevents ground loops and reduces electrical noise.
This isolation protects the backplane from field wiring faults.
Thus, the module maintains reliable operation even with noisy input signals.

Terminal Block and Wiring Specifications

The 1769-IQ16F uses a removable terminal block for easy field wiring.
For the replacement terminal block, order catalog number 1769-RTBN18 separately.
Wire type must be copper rated for 90 degrees Celsius minimum.
For solid wire, acceptable sizes range from 22 to 14 AWG (American Wire Gauge).
For stranded wire, the Allen-Bradley 1769-IQ16F also accepts 22 to 14 AWG sizes.
Use terminal screws torqued to 6 pound-inches for secure connections.
Thus, field wiring remains reliable under vibration and temperature cycling.

Environmental Specifications

The 1769-IQ16F operates reliably across standard industrial conditions.
Operating temperature spans 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).
Relative humidity tolerance reaches 5 to 95% non-condensing for humid environments.
For storage, the module tolerates wider temperature extremes as standard.
The Allen-Bradley 1769-IQ16F requires installation in a protected enclosure.
Enclosure heaters or coolers may control temperature for extreme ambient conditions.
Thus, the module suits most factory automation environments without special handling.

Mounting Options and Mechanical Design

The 1769-IQ16F supports both DIN rail and panel mounting options.
For DIN rail mounting, simply clip the module onto standard 35mm rail.
For panel mounting, use screws through the integrated mounting tabs.
Dimensions measure 118 x 35 x 87 mm (4.65 x 1.38 x 3.43 inches).
The Allen-Bradley 1769-IQ16F uses standard 1769 mechanical locking mechanisms.
This mechanism secures the module to adjacent modules and the backplane.
For removal, use a screwdriver to release the locking tabs from the adjacent module.

Certifications and Standards Compliance

The 1769-IQ16F carries multiple certifications for global deployment.
c-UL-us certification covers UL Listed Industrial Control Equipment for US and Canada.
CE compliance includes EN 61000-6-2 for Industrial Immunity standards.
CE compliance also includes EN 61000-6-4 for Industrial Emissions standards.
RCM certification meets Australian Radiocommunications Act requirements.
EAC certification complies with Russian Customs Union TR CU 020/2011.
Thus, the Allen-Bradley 1769-IQ16F ships worldwide without compliance issues.
