8 Channel Voltage Input & Current Input Analog Input Data Acquisition Module,
communicable over Modbus RTU and RS-485. M-7017C is Current Input Version
M-7017C is a 8-channel Analog Input data acquisition remote I/O module that
supports Modbus RTU. It supports both current input types +/-20mA, 0-20mA and
4-20mA(requires optional external 125ohm resistor). With 240Vrms over-voltage
protection and 4KV ESD Protection for each channel, it offers a safe and
cost-effective solution for your data acquisition needs. It can be remotely
controlled using a set of commands called DCON protocol. With the Modbus RTU
protocol, it can easily communicate with most SCADA/ HMI software and PLCs.
