Version Comparision
There are two versions of the analog input series, one defaults to current input, and the other defaults to voltage input.
1. Modbus RTU Analog Input 8CH, 8-ch current mode, 0~20mA. Measurement range: 0~5V/1~5V; 0~20mA/4~20mA
2. Modbus RTU Analog Input 8CH (B), 8-ch voltage mode, 0~10V. Measurement range: 0~10V/2~10V. 0~20mA/4~20mA
Features
Configurable device address (1~255), multi devices can be cascaded on RS485 bus
Onboard voltage regulator, supports 7~36V wide range power supply
Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference
Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
Supports 12-bit high-precision acquisition with multiple range input modes, supports single-ended/differential input, supports voltage and current simultaneous acquisition
