M-7055
8 Channel Isolated Digital Input (Counter, Dry Contact: Source, Wet Contact: Sink or Source) and 8 Channel Isolated Digital Output (Source) Data Acquisition Module, communicable over Modbus RTU and RS-485, supports operating temperatures from -25 ~ 75°C
Features
The M-7055 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.
