Key benefits Accurate signal simulation for installation, debugging, maintenance, and repair — generates 0–10 V and 0–22 mA outputs to test sensors, transmitters, and control loops. Saves time on repeated tasks — store and recall frequently used values with a single click, so you don’t need to re-enter common settings after power cycles. Reliable field and bench use — pluggable terminal blocks and a robust control knob make connections secure and adjustments fast. Flexible power choices keep you working in any environment — external DC, USB, or a built-in rechargeable battery (Type 1 model). What the SG-002 does Produces voltage output from 0 to 10 V and current output from 0 to 22 mA, including full compatibility with the 4–20 mA industry standard for sensor and transmitter testing. Acts as a precision reference during loop checks, transmitter calibration, and control system troubleshooting. Key features Outputs: 0–10 V and 0–22 mA (compatible with 4–20 mA systems). Connections: pluggable terminal blocks for secure, easy wiring. Display: 4-digit high-definition display with 8 adjustable brightness levels for clear readings in any lighting. Controls: premium aluminum knob cap with electroplated buttons for durable, precise operation. Model note: SG-002 current transmitter for accurate signal simulation. Memory: save voltage or current values using the encoder; the display shows "..." when a value is saved and automatically recalls saved settings after restart. Power options: External DC 15–30 V (can share 24 V supply with PLC devices). USB DC 5 V (works with power banks, chargers, and computer USB ports). Built-in rechargeable lithium battery (available on Type 1 model) for untethered field work. Why professionals choose it Minimizes downtime: quick simulation and recall of signals speeds troubleshooting and reduces repetitive setup. Versatile compatibility: handles standard 4–20 mA loops and common voltage tests without extra adapters. Durable, service-ready design: industry-style terminal blocks and quality controls stand up to repeated use. Typical applications On-site loop testing and commissioning: simulate 4–20 mA sensors while checking PLC input scaling and control logic; share a 24 V control power source for convenient wiring. Sensor and transmitter bench calibration: set precise current or voltage outputs to verify transmitter linearity, zero/span adjustments, and device responses. Field diagnostics and maintenance: use USB power bank or the Type 1 internal battery to carry out signal checks in remote panels or during shutdowns without needing mains power. Technical reminders Model: SG-002 current transmitter. Power options and battery availability: external DC 15–30 V, USB DC 5 V, and built-in rechargeable lithium battery on the Type 1 model. Memory indicator: saved settings are acknowledged with "..." and automatically recalled after restart. The SG-002 provides straightforward, reliable signal generation and memory functions in a compact, jobsite-ready package for engineers and technicians working with voltage and 4–20 mA current loops.
