The I-7044 offers 4 channels for digital input and 8 channels for digital output, each of which features Photocouple isolation. The I-7044 supports sink-type output using open collector and sink- or source-type input via wire connections. All input channels are able to be used as 16-bit counters. There are options to enable both power-on and safe values . The I-7044D has 12 LED indicators for DI and DO channel status monitoring. 3750 Vrms intra-module isolation are standard. The hardware specifications for the M-7044 are the same as the I-7044 and both support the Modbus RTU and DCON protocols which can be configured via software.
