Information About 1746-NI4
The 1746-NI4 is part of the SLC 500 product family, designed to expand controller functionality with high-resolution analog inputs. It features four non-isolated differential input channels that can be configured for either –20 to +20 mA current loops or –10 to +10 VDC voltage signals. Using Delta-Sigma modulation, the module provides data ranges of –16,384 to +16,384 (current) or –32,768 to +32,767 (voltage), ensuring precise digital conversion. It achieves typical accuracy of ±0.284% full scale at 25 °C, with drift compensation across operating temperatures. Current input impedance is 250 Ω, while voltage input impedance is 1 MΩ, with built-in overvoltage protection up to 220 V DC or AC RMS. The module requires 25 mA at 5 VDC and 85 mA at 24 VDC from the backplane. It includes LED indicators for channel and module diagnostics, improving troubleshooting and reducing downtime. Compatible with both fixed and modular SLC 500 controllers, the 1746-NI4 supports scalable control architectures across diverse industries.
Key Features:
- Design: Analog input module for SLC 500 systems with four differential channels.
- Signal Ranges: Selectable per channel – ±20 mA current or ±10 VDC voltage.
- Resolution: 16-bit digital conversion with Delta-Sigma modulation.
- Accuracy: ±0.284% of full scale at 25 °C; ±0.504% at 60 °C.
- Impedance: 250 Ω for current inputs; 1 MΩ for voltage inputs.
- Protection: Continuous overvoltage protection up to 220 V AC/DC.
- Backplane Current: 25 mA at 5 VDC and 85 mA at 24 VDC.
- Diagnostics: Channel and module status LEDs with controller diagnostic reporting.
- Integration: Compatible with both fixed and modular SLC 500 controllers.
- Applications: Suitable for monitoring process variables in manufacturing, utilities, and industrial automation.
The 1746-NI4 provides precise and flexible analog measurement capability, making it a reliable choice for integrating process signals in SLC 500 control systems.
