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

The M-7045D supports sourcetype output, while the M-7045D-NPN supports sink-type, and both are equipped with short circuit protection. There are options to enable both power-on and safe values, and 16 LED indicators that can be used to monitor the status of the digital output channels. 4 kV ESD protection, 4 kV EFT protection, 3 kV surge protection for power input and 3750 VDC Intra-module isolation are standard.
The M-7045D device is 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.
