Physical properties:
Installation method: Rack-mounted, compatible with ControlLogix racks (such as 1756-A4, A7, A10, A13, A17).
Terminal block: Compatible with detachable terminal blocks (RTB), such as 1756-TBNH (20-pin screw terminal) or 1756-TBSH (20-pin spring clip terminal).
Pre-wired cables: Support Bulletin 1492 pre-wired cables (such as 1492-IFM20F, 1492-IFM20D24A-2).
Enclosure type: Open type (IP20 protection grade).
Display: The front panel of the module is equipped with 16 LED indicator lights for input status (yellow indicates input activation), as well as an OK status indicator light (green indicates normal, flashing red indicates communication issues, and red indicates module failure).
Environmental conditions:
Operating temperature: 0°C to 60°C

Non-operational impact: 50G.
Surge immunity: The signal port can withstand surges from 2 kV lines to ground.
Certification:
Compliant standards: CE, UL, CSA, C-Tick, CCC, KC, MARINE, RCM.
Programming and Configuration
Compatible software: Studio 5000 Logix Designer (formerly RSLogix 5000), used for module parameter setting, configuration of Change of State (COS), and adjustment of input filtering time.
Function
Medium-density input: It provides 16 AC input channels (10-30V AC), divided into 2 groups (8 points in each group), suitable for medium-density input scenarios. Compared with 1756-IA32 (32 channels), it is more suitable for smaller-scale applications.
Flexible communication format:
Support multiple data formats:
Standard input data format: Return fault and input data.
CST timestamp input data format: Returns input data and change timestamp, suitable for sequential events (SOE) applications.
Rack-optimized data format: Collect digital word data from remote racks and convert it into rack images.
Only listen in mode (including standard, CST timestamp and rack-optimized format).
Supports EtherNet/IP or ControlNet networks, adopts Producer/Consumer technology, and shares input information with the ControlLogix controller.
State Change (COS) function: Supports user-configured state change (Change of State). When the state of the input signal changes, it immediately triggers logical execution, bypassing the normal scanning cycle of the processor, and is suitable for applications with rapid response.
Status monitoring
Equipped with LED diagnostic indicator lights:
OK indicator light: Green indicates normal operation, flashing red indicates communication issues, and red indicates that the module needs to be replaced.
16 input status indicator lights: Yellow indicates input activation.
Supports user-configurable filtering time (0, 1, 2, 9 or 18 ms), optimizes input signal processing, and meets the requirements of fast switching or noise reduction.
Modular design
Supports RIUP, Removal and Insertion Under Power, which is convenient for maintenance and replacement.
Connect the on-site wiring through the RTB (1756-TBNH or 1756-TBSH) or 1492 interface module (IFM) to simplify the installation.
Support Electronic Keying to prevent incorrect module replacement.
Support multiple input devices:
Compatible with a variety of AC input devices, such as buttons, limit switches, relay contacts, etc., suitable for 24V AC systems.
If DC signals are to be used, appropriate intermediate circuits need to be installed.
High reliability
Inter-group isolation and isolation to the backplane input reduce the risk of electrical interference and enhance system stability.
The design meets the requirements of industrial environments, is resistant to high temperatures, high humidity and vibration, and is suitable for harsh environments.
Application scenarios
Manufacturing industry: It is used to monitor AC digital signals on production lines, such as the status of buttons, proximity sensors or relays, and is suitable for automotive manufacturing, packaging lines or electronic assembly.
Process control
It is applied in the chemical, petroleum and natural gas, pharmaceutical and food and beverage industries to monitor the status of switches or valves powered by AC.
Suitable for process control systems that require medium-density input.
Safety interlock: In the safety system, detect the status of the emergency stop button or safety relay, trigger a safety shutdown or interlock operation, and isolate between groups to ensure signal reliability.
Sequential Event Recording (SOE) : Supports the CST timestamp data format and is suitable for applications that require recording the sequence of events, such as power systems or critical mission monitoring.
Distributed control system: Integrated into distributed I/O systems through ibanet/IP or ControlNet networks, it is suitable for large factories or remote monitoring applications, such as the PlantPAx DCS platform.
Traditional system maintenance: 1756-IN16 is often used for the maintenance or expansion of existing ControlLogix systems, especially suitable for scenarios that require AC input.
