Allen-Bradley 1769-IQ16 Input Module
Description
Sixteen field inputs for a Compact I/O installation
The Allen-Bradley 1769-IQ16 is a 16-point DC input module in the 1769 Compact I/O range. Its inputs are arranged in two groups of eight. The module receives field signals from the connected devices; it should be distinguished from a DC output module or a high-speed-counter module with a similar housing.
Input voltage limits depend on ambient temperature. The manufacturer lists 10–30 V DC at 30 °C and 10–26.4 V DC at 60 °C. This distinction matters when checking the field supply and cabinet temperature for a replacement.
Technical specifications
| Parameter | Specification |
|---|---|
| Manufacturer / family | Allen-Bradley / 1769 Compact I/O |
| Catalog number | 1769-IQ16 |
| Function | DC digital input module |
| Input points / grouping | 16 / two groups of eight |
| Operating input voltage at 30 °C | 10–30 V DC |
| Operating input voltage at 60 °C | 10–26.4 V DC |
Check the controller and I/O bank
The Compact I/O specification describes applications with 1769 CompactLogix, MicroLogix 1500 expansion and assemblies using the appropriate DeviceNet or Ethernet adapter. The installed controller or adapter, I/O arrangement and power-bank design determine the actual installation.
Record the module position, connected field devices, terminal-block wiring and cabinet temperature before selecting a replacement. The complete IQ16 reference matters: an IQ16F or a higher-point-count input execution has a different specification.
Documents and quotation enquiries
The manufacturer Compact I/O technical data includes the exact IQ16 table and associated wiring diagram. Send the 1769-IQ16 reference, quantity, controller or adapter code, field supply and photographs of the installed module and terminals.

About brand
Catalog numbers beginning 1756, 1734, 1746 or 5069 are read at a glance by anyone who maintains Allen-Bradley control panels. The brand, the control hardware name of Rockwell Automation, dates back to 1903 in Milwaukee, USA. Seven Star LLC sources and supplies Allen-Bradley PLC and I/O modules, communication adapters and PowerFlex drives for plants in Oman, matching catalog number, series letter and firmware against the manufacturer's documentation.
Allen-Bradley product families listed here
Current controller platforms on this page are ControlLogix, with the 1756-L85E ControlLogix 5580 controller and the 1756-PA72 chassis power supply, and CompactLogix 5380, with the 5069-L320ER and 5069-L340ERM. Distributed I/O is represented by POINT I/O: the 1734-AENTR dual-port EtherNet/IP adapter and the 1734-IB8 digital input module. Allen-Bradley drives listed are the PowerFlex 525 and PowerFlex 755. For installed systems there are SLC 500 parts: the 1746-A10 chassis, 1746-NI16I analog input module, 1747-ASB remote I/O adapter, 1747-KE interface and 1747-M13 memory module. A Trusted TMR digital input module (T8403) is also listed.
Where Allen-Bradley hardware is used
ControlLogix and CompactLogix controllers run packaged equipment and plant utilities: compressor and pump skids, water and wastewater plants, power distribution, material handling and packaging lines. PowerFlex drives control pumps, fans and conveyors. Across the GCC, a large base of SLC 500 racks is still running, and Allen-Bradley spare parts for these systems are a frequent request.
Ordering Allen-Bradley modules and drives: what we need
Send the full catalog number, the series letter and, for controllers and communication modules, the firmware revision printed on the side label. Compatibility with an existing project depends on these. For PowerFlex drives, give the complete catalog string, which encodes voltage, current rating, enclosure and options, plus the motor nameplate data. For SLC 500 parts, tell us the rack size and processor so that we can check slot and power supply loading in the manufacturer's manuals. A label photo avoids most mistakes.
