Feature: 1. Device Cascade: Support setting device address (1‑255) to cascade multiple devices via RS485 bus. On board voltage regulator chip, support 7‑36V wide voltage supply, safer to use. 2. Power Supply Isolation: Analog output module has on board integrated power supply isolation, which can provide stable isolation voltage without additional power supply at the isolated end. 3. Signal Isolation: Industrial analog output module has on board integrated magnetic coupling isolation, signal isolation, high reliability and strong anti interference. 4. Safety Guard: On board self recovery safety wire and transient voltage suppressor tube, can effectively suppress the surge voltage and transient voltage peak in the circuit, prevent overcurrent and overvoltage, thunder and static electricity. 5. Easy To Use And Install: 12 bit DA conversion, using high accuracy resistors, more accurate output data. Stable output without crash, rail housing design, support stacking combination, easy to install.
