Features:
- High-resolution 16-bit DAC enables precise voltage output control across all channels.
- Fast 1 ms response time supports dynamic and real-time process adjustments.
- Robust electrical isolation and industrial tolerance ensure reliable operation in harsh environments.
The Allen-Bradley 1746-NO8V plays a critical role in industrial automation systems where precise analog output signals are required to control actuators, drives, and other field devices. Voltage-based output modules like this are widely used in process industries such as chemical, oil and gas, and manufacturing, where accuracy directly affects product quality and operational efficiency. With eight independent channels, the module supports simultaneous multi-point control, reducing the need for additional hardware.
Functionally, the Allen-Bradley 1746-NO8V converts digital signals from the PLC into analog voltage outputs using a 16-bit D/A converter. This allows fine control over output signals, ensuring that connected equipment receives accurate and stable input. The module supports proportional scaling and maintains low non-linearity, making it suitable for applications requiring consistent signal integrity over time. The R-2R ladder architecture further enhances output stability.
From an application perspective, the Allen-Bradley 1746-NO8V fits well into systems requiring reliable analog output under varying environmental conditions. Its compatibility with standard SLC chassis and flexible installation options simplify system design. Combined with strong vibration and shock resistance, as well as support for shielded wiring, the module ensures dependable performance in demanding industrial environments where durability and precision are essential.
The 1746-NO8V Allen-Bradley SLC 8 Point Analog Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Valve Control: Provides continuous electrical signals for proportional control valves and electro-hydraulic servo valves, achieving precise closed-loop linear control of flow and level.
- Variable Frequency Drive (VFD): Remotely inputs voltage setpoints to various industrial VFDs to adjust the operating speed of large motors and pump sets.
- Pressure Control: Widely used in hydraulic presses and injection molding equipment, controlling proportional pressure valves in hydraulic circuits by real-time correction of analog voltage.
- Servo Positioning: Converts position commands calculated by the PLC into analog signals in real time and sends them to the servo driver to drive the actuator for precise positioning.
- Slot Configuration: The module can be inserted into any standard SLC 500 rack slot except slot 0 (main CPU slot).
- Format Selection: Supports both Class 1 (simple data) and Class 3 (extended data with status) operating formats.
- Jump Settings: Features an onboard power selection jumper, allowing switching between internal backplane power supply and external 24V DC power supply as needed.
- Software Adjustment: Independent data range configurations for each of the 8 channels can be performed directly in the I/O tree using RSLogix 500 or Studio 5000 software.
- LED Status: The module panel is equipped with clear channel LEDs and a system OK indicator, providing real-time feedback on the operating status of individual channels and the overall system.
- Fail-Safe: Allows users to preset channel outputs to zero or retain their last value when the PLC is in programming or communication interruption mode.
- Overflow Monitoring: When used with Class 3 format, the system automatically reports diagnostic flags such as over-range and under-range readings in the backplane data words.
- Status Inquiry: Engineers can extract underlying error codes transmitted from the baseboard in real time from the PLC controller's tags or data tables.
