Product Description

Output Modules are engineered for reliable, high-power switching and precise signal generation:

• Digital Output (DO): Switches power ON or OFF to binary actuators like solenoids, contactors, and indicator lamps. Digital outputs typically use either relays (for high current/voltage flexibility) or transistors (for high-speed switching).

• Analog Output (AO): Generates a continuous, variable electrical signal (usually $0-10 text{V}$ or $4-20 text{mA}$) to control proportional devices like variable speed drives, control valves, or specialized measuring equipment. The module performs a high-resolution Digital-to-Analog (D/A) conversion.

• Overload Protection: Includes internal short-circuit and thermal overload protection to prevent damage to the module and the external wiring.

• Galvanic Isolation: Provides electrical separation between the sensitive internal control logic and the external power circuits of the actuators.

• Diagnostics: Offers advanced diagnostics, such as monitoring for short-circuits to ground/L+, wire breaks, and actuator failures on a per-channel basis.

Product Parameters

The technical parameters are crucial for ensuring the module is correctly matched to the power requirements of the actuators:

Product Advantages

• High Actuator Control: Provides the necessary power and interface to reliably switch and control a wide variety of industrial actuators.

• Safety and Protection: Integrated short-circuit and overload protection features automatically protect the control system hardware from fault conditions in the field wiring.

• Precision Control (AO): Analog output modules offer high resolution, allowing for precise and smooth proportional control of devices like variable speed drives and flow valves.

• Maintenance Efficiency: Detailed channel-level diagnostics immediately report where a fault has occurred (e.g., a shorted solenoid), drastically simplifying maintenance and repair.

Important Considerations (Notes)

• Current Sizing (DO): Ensure the module’s output current per channel is rated higher than the peak current required by the connected actuator (e.g., inrush current of a solenoid).

• Load Type (DO): Use relay outputs for switching AC or high-voltage loads and for devices requiring electrical isolation, while using transistor outputs for fast-switching, low-voltage DC loads (e.g., pulse-width modulation).

• AO Scaling: The module’s analog output must be correctly scaled and configured to match the input requirement of the receiving device (e.g., setting $4 text{mA}$ as $0%$ flow and $20 text{mA}$ as $100%$ flow).

• Wiring Separation: Maintain physical separation between power and control wiring to prevent noise injection, especially for sensitive analog output signals.

Product Applications

Output Modules are crucial for commanding all types of physical actions in an automated environment:

• Digital Outputs (DO): Used to actuate solenoid valves (to start/stop flow), energize motor contactors (to start/stop motors), control indicator lamps (for status indication), and trigger alarms.

• Analog Outputs (AO): Used for proportional control of control valves (to regulate flow), setting the speed reference for variable speed drives, modulating the power output of heaters, and controlling the position of linear actuators.
