DAM114 - 2CH Analog Data Acquisition Module（2 AIN input）
The DAM114 remote data acquisition module is designed for harsh industrial applications and is used in a wide range of industrial automation measurement, for measuring 2 channel analog input(0-5V,0-10V,0-20mA,4-20mA), and can transmit in ASCII data format to any RTU (Remote Terminal Unit), SCADA, data monitoring, data loggers, PLC’s, process controllers and instrumentation that supports Modbus RTU Protocol over RS485 serial port. Powered up by 9~36VDC.
Introduction
The DAM114 remote data acquisition module is designed for harsh industrial applications and is used in a wide range of industrial automation measurement, for measuring 2 channel analog input (0-5V,0-10V,0-20mA,4-20mA), and can transmit in ASCII data format to any RTU (Remote Terminal Unit), SCADA, data monitoring, data loggers, PLC’s, process controllers and instrumentation that supports Modbus RTU Protocol over RS485 serial port. Powered up by 9~36VDC.
2 analog inputs, which can measure 4~20mA, 0-20mA, 0-10V or 0~5V signals from transmitter, current, voltage, pressure, temperature, and power. 1 RS485 supports standard MODBUS-RTU communication protocol.
The DAM series remote data acquisition module can also be used as an expansion module of GSM 3G 4G RTUS27x, which can expand the number of I/O ports of S27x to meet the needs of different applications.
