Industrial 8-Ch Analog Acquisition Module, 12-bit High-Precision, DC 7~36V Wide Voltage Power Supply, Modbus RTU Protocol, 8-CH Voltage Mode, 0~10V (($34.55Value)

Description

Supports sending Modbus RTU protocol commands via RS485 to acquire data from 0~20mA sensor. Rail-Mount Support, Supports 35mm standard guide rail, with rail-mount buckle, easy to install. Onboard power and signal dual isolation for RS485 communication, provides stable isolation voltage, features high reliability and strong anti-interference performance. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable current and voltage output, provides over-current and over-voltage proof, improves shock-proof performance, suitable for the industrial environments with high requirement. Supports current acquisition. Wider Measurement range, 8-ch analog acquisition interfaces, voltage and current acquisition is switchable via jumper. Multiple Ranges Configurable via Software. Version Comparision

There are two versions of the analog input series, one defaults to current input, and the other defaults to voltage input.
