All modules in the 7045 series offer 16 digital output channels, each of which features Photocouple isolation. The I-7045(D)/M-7045(D) supports sourcetype output, while the I-7045(D)-NPN/M-7045(D)-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-7045(D)/M-7075(D)-NPN has the same hardware specifications as the I-7045(D)/I-7045(D)-NPN, but provides additional support for the Modbus RTU protocol as well as the DCON protocol.
