A-Series I/O is a cost effective remote I/O system. It is a good choice for applications that need only a few I/O points at multiple locations, or a mixture of signals at a location. A-Series modules are available for Ethernet or serial RS-485 connection to any SoftPLC PAC, SoftPLC Web Studio HMI/SCADA system, or any controller or software product that supports the supported driver for the specific A-Series module(s). Also available in this product line are Ethernet switches and media converters.
