The M-7018Z is a 10-channel voltage and current thermocouple input data acquisition module. It is communicable over Modbus RTU and RS-485 with High Over Voltage Protection. Supports operating temperatures between -25 to 75°C (-13F ~ 167F). M-7018Z comes with a DB-1820 Daugther Board that supports Modbus RTU. They can be remotely controlled using a set of commands called DCON protocol. With the Modbus RTU protocol, it can easily communicate with most popular SCADA software and PLCs.
