The Allen-Bradley 1746-IG16 SLC 500 module provides sixteen digital input channels. This unit interfaces with TTL and BCD signal devices. The module operates within a 4.5 to 5.5 Volts DC range. It occupies a single slot in the SLC 500 chassis. This module offers a unique inversed logic functionality. A low voltage signal between -0.2 and 0.8 VDC turns the input ON. This design simplifies integration with specific electronic ports.
Expert Technical Evaluation & Performance Review
The 1746-IG16 delivers a fast signal delay for precise control. The ON state delay measures just 0.25 milliseconds. The OFF state delay is a quick 0.5 milliseconds. This module draws 140 milliamps from the 5V backplane. It dissipates a total power of only 1 Watt. Each input point consumes just 0.02 Watts. These specs ensure minimal heat generation in your panel.
This module provides robust electrical isolation for signal integrity. It features electro-optical isolation tested at 1500 Volts. This isolation protects the control logic from input transients. The unit also meets NEMA ICS 2-230 noise immunity standards. This rating ensures reliable operation in electrically noisy environments. The module withstands 30G of operational shock. It also handles 2.5G of vibration from 57 to 200 Hz.
The 1746-IG16 operates reliably in harsh industrial conditions. It functions in ambient temperatures from 0 to 60 degrees Celsius. The module tolerates 5 to 95 percent non-condensing relative humidity. You can store it safely between -40 and 85 degrees Celsius. The unit holds CSA and UL certifications for safety. It also carries a Class I, Division 2 hazardous location rating.
Step-by-Step User & Installation Guide
Follow these steps for a proper and safe installation. First, handle the module only by its ends. Avoid touching the metallic surfaces to prevent ESD damage. Second, install the module into any available slot. Remember that slot zero is reserved for the SLC 500 controller. Third, limit all signal wiring to 15 meters or 50 feet per point. Use only low power DC wiring for the connections.
Fourth, do not run signal wiring in the same duct as communication cables. This practice prevents electrical interference and data errors. Fifth, use the 1746-RT25B removable terminal block for connections. For I/O, utilize the 1746-HT or 1746-HCA cables. An octal kit, part number 1746-RL42, is also available. Finally, group similar module types together in the chassis. This grouping simplifies troubleshooting and improves wiring organization.
