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.
Analog Input
115S-11: 0
115S-12: 4 “floating”/8 commoned (0-20mA/0-10V)

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.
