M-7051
16 Channel Isolated Digital Input (Counter) Data Acquisition Module, communicable over Modbus RTU and RS-485. Supports operating temperatures from -25 to 75°C
Features
The M-7000 series is a family of 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.
- Communication Interface: RS-485
- Channels: 16
- Din Rail Mount
- D/I can be used as counter
