The I-7050 series of modules offers channels for digital input and 8 channels for digital output, each of which are non-isolated. The I-7050 supports sink-type output using an NPN open collector, and source-type input. All input channels are able to be used as 16-bit counters. There are also options to enable both power-on and safe values. The I-7050D has 15 LED indicators that can be used to monitor channel status. The M-7050 has the same hardware specifications as the I-7050, but provides additional support for the Modbus RTU protocol as well as the DCON protocol.
