The ELPRO 115S series allows end users to readily accommodate changing I/O needs as project specifications evolve. The 115S series can be used with ELPRO transceiver-based I/O, Gateway, Ethernet and Serial products to expand input and output count or act as Modbus slave I/O to connect other field devices.
Connected via RS485 and communicating ELPRO or Modbus protocols, the 115S series is available in three versions of I/O count and multiple 115S products may be daisy-chained to accommodate changing application needs.
