Theme Option A: Product Procurement & Buyer Guide
Why Choose the 1746-IC16 for Your System?
The 1746-IC16 serves as a robust solution for 48V DC sensing environments. This module accepts a voltage range from 30 to 55 Volts DC. It operates reliably in temperatures up to 60 degrees Celsius. Procurement teams value its approval for Class 1, Division 2 hazardous locations. This certification makes it suitable for harsh industrial areas.
Understanding the 48V DC Sinking Architecture
This module uses a sinking input topology for its 16 channels. Each input draws a nominal current of 4.1 milliamps at 48 Volts DC. The off-state current leakage measures only 1.5 milliamps. This low leakage prevents false signals from sensor leaks. The module provides an off-state voltage loss of 10 Volts DC. This specification ensures clear distinction between on and off states.
Critical Electrical Specifications for Engineers
The 1746-IC16 draws 0.085 Amps from the 5 Volt DC backplane. It requires zero current from the 24 Volt DC backplane supply. The signal delay for both on and off transitions is 4 milliseconds. This fast response supports high-speed counting applications. The module uses a Removable Terminal Block (RTB) for wiring. This design simplifies field wiring and future module replacements.
Environmental and Physical Durability Factors
This module withstands operational shock of 30 G for 11 milliseconds. It resists vibration of 1.0 G across a 5 to 200 Hz range. The operating humidity range spans 5 to 95 percent non-condensing. Storage temperatures range from -40 to 85 degrees Celsius. This ruggedness makes the 1746-IC16 ideal for demanding factory floors.
Ensuring Electrical Isolation and Safety
The 1746-IC16 provides 1500 Volts AC isolation between the backplane and inputs. This isolation protects the controller from voltage spikes on field wiring. The dielectric withstand rating is also 1500 Volts AC for 60 seconds. This high isolation level meets stringent industrial safety standards. It provides a safe barrier for maintenance personnel.
