Horner Automation HE800DAC101B 4-Channel Analog Voltage Output Module

The Horner Automation HE800DAC101B is a compact, high-performance 4-channel analog voltage output module designed for integration into Horner's SmartStack I/O systems, commonly used in programmable logic controllers (PLCs) and operator control stations (OCS). This module provides precise voltage outputs ranging from -10V to +10V DC, making it ideal for applications requiring accurate control of analog devices such as variable speed drives, valves, and actuators in industrial automation, process control, and manufacturing environments. Key features include 12-bit resolution for fine-grained control, plug-and-play compatibility with Horner OCS controllers, and robust construction suitable for harsh industrial settings. Advantages over similar products include its modular design for easy expansion, cost-effectiveness compared to standalone DAC units, and seamless integration with Horner's all-in-one control solutions, reducing wiring complexity and setup time. However, it may require specific Horner base units for operation, limiting compatibility with non-Horner systems, and its output load is capped at 100 ohms, which could necessitate additional amplification for high-impedance applications. Based on attached images, the unit appears to be in used condition with minor wear, including attached green wires on the terminal block, but no visible damage to the circuit board or housing. Faceplate details confirm the model as HE800DAC101B with UL listing (E180220) and electrical ratings of +/-10VDC outputs, max temp 60°C. No parent/child assets are evident. Estimated market price for a used unit ranges from $150-250 USD, based on recent sales data from industrial surplus sites like eBay and Radwell.
