M-7022
2 Channel Current Output, Voltage Output, and Analog Output Data Acquisition Module. Communicable over Modbus RTU and RS-485. Supports operating temperatures between -25°C to 75°C (-13°F ~ +167°F).
Features
The M-7022 device is a network data acquisition and control modules that support 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/ HMI software and PLCs. Photo-isolation: 3750 Vrms
