The M-7041-A5 provides 14 channels for high voltage digital input, each of which features photocouple isolation. The input voltage level could be as high as 150V. In addition, either sink- or source-type digital input can be selected via wire connections, and all channels are able to be used as 16- bit counters. 4 kV ESD protection and 3750 VDC intra-module isolation are standard. The M-7041-A5 support both the Modbus RTU and DCON protocols, which can be confi gured via software.
