M-7045
16 Channel Source Type Isolated Digital Output (Counter), Data Acquisition Module, communicable over Modbus RTU and RS-485, supports operating temperatures from -25 to 75°C
Features

The M-7045 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.
- Communication Interface: RS-485
- Digital Output Channels: 16
- Din Rail Mount
- Direct drive power relay module
- Short circuit protection
