Rossonix Co., Limited, a trusted supplier with over a decade of experience in the industrial automation market, proudly presents the Allen Bradley 1746-IG16 SLC500 System 16 ch-TTL Input Module. This genuine module is engineered to deliver reliable and precise digital input acquisition for demanding control applications. By leveraging our extensive supply network and commitment to quality, we ensure that every 1746-IG16 you receive meets the rigorous standards expected by automation professionals worldwide. Whether you are upgrading an existing SLC500 system or building a new one, this module offers the performance and dependability you need to keep your operations running smoothly.

The 1746-IG16 is a 16-channel TTL input module designed specifically for the Allen-Bradley SLC500 programmable logic controller (PLC) platform. It accepts 5V TTL-compatible signals from sensors, encoders, or other digital devices, making it an ideal choice for high-speed counting, position sensing, and communication interfaces. With its robust design and seamless integration into the SLC500 rack, this module simplifies wiring and reduces installation time. Below, we break down its key features, technical specifications, and the tangible benefits it brings to your automation systems.

Key Features & Technical Specifications

16-Channel TTL Digital Input: Each channel accepts TTL-level signals (0–5V), ideal for interfacing with high-speed encoders, pulse generators, and other logic-level devices.
Backplane Compatibility: Plugs directly into any SLC500 1746 I/O chassis, supporting both local and remote I/O configurations.
High-Speed Capability: Designed for applications requiring fast update times, such as position counting and event capture.
LED Status Indicators: Individual green LEDs for each input channel provide immediate visual feedback of signal presence, simplifying troubleshooting.
Isolated Inputs: Optical isolation between the field wiring and the backplane helps protect the PLC from electrical noise and ground loops.
Removable Terminal Block (RTB): Facilitates easy wiring and module replacement without disconnecting field wiring.
Compact Form Factor: Occupies a single slot in the SLC500 chassis, conserving space for other modules.

Parameter	Specification
Number of Inputs	16 (sinking or sourcing depending on wiring configuration)
Input Voltage Range	5V DC nominal (TTL compatible)
Logic Levels	High: 2.0–5.5V, Low: 0–0.8V
Input Current	Typically 7 mA at 5V (per channel)
Backplane Current Draw	5V: 100 mA typical; 24V: 100 mA typical (consult manual for exact values)
Operating Temperature	0°C to 60°C (32°F to 140°F)
Isolation Voltage	1500V AC between field and backplane (1 minute)
Module Location	Any I/O slot (SLC500 chassis)
Weight	Approx. 0.25 kg (0.55 lb)

Customer Benefits

Seamless Integration: The 1746-IG16 is a direct replacement for existing modules in SLC500 systems, requiring no special configuration or additional software.
Enhanced System Reliability: Optical isolation reduces the risk of damage from electrical surges and improves signal integrity, minimizing false readings.
Increased Productivity: High-speed input capability allows faster data acquisition, enabling more precise control in applications like packaging, material handling, and CNC machines.
Ease of Maintenance: LED indicators and removable terminal blocks simplify diagnostics and module swaps, reducing downtime.
Cost-Effective Expansion: Adding 16 TTL inputs is a budget-friendly way to expand your I/O capacity without replacing the entire control system.

Frequently Asked Questions

Q: Is the 1746-IG16 compatible with all SLC500 processors?
A: Yes, this module is designed for use with any SLC500 processor (5/01, 5/02, 5/03, 5/04, 5/05) that provides the standard backplane interface. It works in both fixed and modular I/O configurations.
Q: What type of field wiring does this module use?
A: The module features a removable terminal block (RTB) with screw terminals suitable for 14–22 AWG (American Wire Gauge) wire. Wiring diagrams are provided in the user manual.
Q: Can I use 24V DC sensors with this TTL input module?
A: No, the 1746-IG16 is designed for 5V TTL signals only. For 24V inputs, you would need a different module such as the 1746-IB16 or 1746-IA16. If you have 24V sensors, consider using an interface converter or signal conditioner.
Q: Does the module require any additional software configuration?
A: Basic configuration can be done through your RSLogix 500 or compatible programming software. You will need to assign the I/O address and set input filter times if required. The module itself is plug-and-play.
Q: What is the maximum cable length for inputs?
A: For reliable TTL signals, we recommend keeping cable lengths under 10 meters (33 feet) to avoid signal degradation. For longer distances, use shielded twisted-pair cable and consider adding line drivers.
Q: Are spare parts or replacement terminal blocks available?
A: Yes, the removable terminal block can be ordered separately (part number 1746-N2 or equivalent). Rossonix can supply these upon request.
Q: What kind of warranty do you offer on this module?
A: We provide a standard 12-month warranty against manufacturing defects. Extended warranty options are available upon request. All modules are tested before shipment.
Q: Can I use this module in a remote I/O rack?
A: Yes, the 1746-IG16 can be used in both local and remote I/O racks as long as the communication adapter (e.g., 1747-SN) is properly configured.
