The ELPRO 115S series is designed to allows end users expand input and output count or act as a Modbus® slave I/O to connect other field devices which accommodate the change in I/O as the project needs evolve. It can be used with ELPRO transceiver-based I/O, gateway, Ethernet, and serial products.
• Provides several I/O port variations for expanding applications
• Combine units (daisy chain) to accommodate additional I/O needs
• Serial modem expansion I/O for ELPRO transceiver I/O, gateway, and Ethernet products
• Modbus RTU slave I/O expansion capability
