KLAYERS Industrial 4-Channel DC Monitoring Module, 16-Bit High-Precision Voltage & Current Acquisition,Modbus RTU, 7-36V Wide Power

Multi-Channel High-Precision Monitoring: Features 4 DC channels with 16-bit high-precision acquisition and a 0.002 1% current sense resistor, enabling accurate bidirectional measurement of voltage (up to 36V), current (up to 8A), and direct power calculation.
^^ Robust Multi-Stage Protection: Ensures reliability in industrial environments with built-in power isolation, optocoupler signal isolation, resettable fuses, and TVS diodes for surge voltage suppression, over-current/over-voltage proofing, lightningproof, and anti-electrostatic capabilities. ^^ Flexible Wide-Range
Power Supply: Equipped with an onboard voltage regulator that supports a wide 7~36V DC power input, simplifying integration into various systems without requiring extra isolated power supplies. ^^
Easy Integration & Communication: Utilizes the standard Modbus RTU protocol over an RS485 bus, supports configurable device addresses (1~255), and allows for multiple devices to be easily cascaded.
^^ Space-Saving Rail-Mount Design: Housed in a compact, rail-mount case that supports stacking combinations, ensuring easy installation, secure usage, and efficient use of space in control cabinets. Status LEDs provide clear indication of MCU and signal transceiving activity.
