010V / 022mA Signal Output Device — digital voltage and current generator for testing and field calibration Key benefits Provides precise, adjustable analog outputs (0–10 V and 0–22 mA) so you can simulate sensors, drive analog inputs, and verify control loops without relying on live process signals. Portable and flexible power options let you work on benches, in the field, or while traveling: external DC 15–30 V, USB DC 5 V, or a builtin lithium battery (included on Type 2) for uninterrupted operation. Safe, reliable wiring and a clear display reduce setup time and measurement errors: pluggable terminals and robust controls prevent accidental disconnection; a 4‑digit LED with eight brightness levels ensures readable output in any environment. Save and recall values to speed repeat tests: press the encoder knob to store the current voltage or current setting (confirmation appears as '...' after release) and have that value automatically restored on restart. Main features Outputs: selectable analog output 0–10 VDC and current output 0–22 mA for compatibility with PLCs, transducers, actuators, dimmers, and other industrial analog inputs. Display: 4‑digit LED readout with adjustable brightness (levels 1–8) for clear visibility in bright or dim work areas. Power: three supply modes — external DC 15–30 V input, USB DC 5 V connection, or internal lithium battery (Type 2 includes the battery) for flexible deployment. Wiring and controls: secure pluggable terminal, aluminum knob cap, electroplated buttons, and quality film switch design to ensure robust connections and reliable operation in demanding conditions. Data memory: save a voltage or current setting via the encoder knob; saved setting is indicated and restored automatically after power cycling to avoid reconfiguration. Compatibility and performance notes Designed for use with devices and systems that accept 0–10 V or 0–22 mA analog signals, including PLC analog inputs, transmitters, controllers, lighting controls, and process instruments. The 4‑digit display and brightness control aid readability across a variety of environments without requiring external lamps or additional instruments. Typical applications Field calibration: verify and calibrate transmitters, sensors, and looppowered devices on site, using stored output values to repeat checks quickly. System commissioning and troubleshooting: simulate analog inputs to test PLC logic, actuators, and control valves during installation or maintenance. Bench testing and R&D: generate stable voltage or current references when developing, repairing, or certifying analog equipment and lighting dimming systems. What you get Digital 0–10 V / 0–22 mA output device with 4‑digit LED display, adjustable brightness, pluggable terminal connections, aluminum knob cap, electroplated buttons, and film switch design. Type 2 models include a builtin lithium battery; all models support external DC 15–30 V and USB DC 5 V power inputs. Data save and recall via the encoder knob for faster, repeatable testing.
