Output Module Allen-Bradley 1746-NO8V SLC 500 Analog

Product Overview

The Allen-Bradley 1746-NO8V is a reliable analog output module for the SLC 500 family. It provides eight single-ended voltage output channels. Each channel delivers a range of ±10.25V DC. This module uses a 16-bit resolution of 320 µV/count. It offers high accuracy for industrial control tasks. The module includes circuit isolation between field wiring and the backplane. It is tested at 500V DC for safety. LED indicators show module and channel status clearly. The 1746-NO8V is CUL and CE certified for hazardous locations.

Application Scenarios

This module controls modulating devices in industrial processes. It works well with valves and dampers. It also controls Variable Frequency Drives (VFD) and louvers. Engineers use it for precise analog signal control. It fits into any 1746 chassis slot except slot 0. It is ideal for factory automation and process control systems. The module supports various output data formats for flexibility.

Technical Specifications

The module has eight single-ended analog output channels. It offers output voltages of -10 to +10VDC, -10.25 to +10.25VDC, 0 to 10VDC, 0 to 5VDC, and 1 to 5VDC. The resolution is 16-bit or 320 µV/count. Overall accuracy is 0.1% of full scale at 25°C. It is 0.2% of full scale at 60°C. The backplane current consumption is 120 mA at 5V DC. It also uses 160 mA at 24V DC with J4 set to RACK. Power consumption is 5.6W. Update time is 540 microseconds for 8 channels. Step response is 60 milliseconds in and 2.5 milliseconds out. The module operates from 0 to 60°C. It handles 5 to 95% non-condensing humidity. It withstands 30G operational shock and 5G vibration at 10-500Hz.

Installation & Maintenance Guide

Install the module into any available 1746 chassis slot. Do not use slot 0. Set the J4 jumper for RACK or EXT power as needed. Wire the field outputs to the terminal block. Use shielded cables for best signal quality. Check the LED indicators for proper status. Ensure the load resistance is above 1K ohm. The maximum load current is 10 mA. Keep the module within the specified temperature range. Regularly inspect connections for tightness. Replace the module if the LED shows a fault.
