It includes two differential analog input channels that can be individually configured for either current or voltage operation. Current input ranges include –20 to +20 mA with 16-bit resolution, while voltage inputs accept –10 to +10V DC with high accuracy and low drift. The module uses Delta-Sigma conversion for input processing to ensure precision in analog measurement applications. The module also provides two non-isolated analog voltage outputs with a range of –10 to +10V DC. These outputs use an R-2R ladder digital-to-analog converter with 14-bit resolution, making the module suitable for actuator control, analog retransmission, and other analog drive applications. A 2.5 ms step response ensures fast output reaction in process control environments. Key Features: 2 differential analog input channels 2 analog voltage output channels Selectable voltage or current input per channel –10…10V or –20…20 mA input ranges –10…10V analog output range 16-bit input resolution / 14-bit output resolution 512 µs module update time 500V input isolation Rack-mounted SLC 500 design Suitable for mixed analog measurement and control SLC 500 analog combination module with 2 configurable analog inputs and 2 voltage outputs. Designed to install into any SLC 1746 chassis, the 1746-NIO4V draws 55 mA from the 5V backplane and 115 mA from the 24V backplane. It offers 500V field-to-backplane isolation on its input channels and accepts shielded Belden 8761 cable for noise immunity. With configurable channels, high accuracy, and compact size, the module is ideal for mixed analog I/O requirements in SLC 500 systems or as distributed I/O when used with CompactLogix or ControlLogix PACs.
