M-7052D - 8-channel Isolated Digital Input Counter Data Acquisition Module with Display, supports Modbus RTU and RS-485
by ICP DAS
|
|
|
|
8 Channel Isolated Digital Input Counter Data Acquisition Module,
communicable over Modbus RTU and RS-485 with Display, supports operating
temperatures from -25 to 75°C
|
|
|
The M-7052D 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.
- Communicartion Interface: RS-485
- Digital Input Channels: 8
- 6 fully independent channels
- 2 common ground channels
- D/I can be used as counter
- Din Rail Mount
