Product Procurement & Buyer Guide
Understanding the 1746-IC16 Voltage Range

The 1746-IC16 module operates on a temperature-dependent voltage range. You must consider this when designing your control panel environment. At 55°C, the module accepts a range of 30 to 60V DC. At 60°C, this range narrows to 30 to 55V DC. This thermal adjustment ensures reliable switching under varying heat loads.
Key Electrical Specifications for Engineers
This module draws only 0.085A from the 5V DC backplane. It uses no current from the 24V DC backplane supply. The nominal current per input point is 4.1mA at 48V DC. The off-state current leakage is a low 1.5mA, preventing false triggering. These values help you calculate total system power budgets precisely.
Environmental and Hazardous Location Ratings

The 1746-IC16 is approved for standard industrial environments. It also carries certification for hazardous locations rated Class 1, Division 2. This approval covers Groups A, B, C, and D. You can deploy this module in areas with potentially explosive atmospheres. This makes it a versatile choice for diverse industrial sectors.
Signal Integrity and Isolation
This module provides 1500V AC isolation between the backplane and inputs. It withstands this dielectric test for 60 seconds. This high isolation level protects your SLC 500 processor from electrical noise. It also guards against ground loops in demanding factory floor applications.
