115S series

Connected via RS485 and communicating either ELPRO or Modbus protocols, ELPRO’s 115S series expansion products are available in three versions of I/O count and able to be used in the following modes:

  • Expansion I/O for ELPRO 105U/905U wireless I/O units (up to 10 x 115S units can be connected to each wireless unit).
  • I/O capability for ELPRO’s serial and 802.11 wireless Ethernet units (up to 99 x 115S units per wireless unit).
  • Modbus Slave I/O expansion units (up to 99 x 115S units can be connected to each Modbus Master eg PLC).
  • Serial I/O multiplexer - transfer I/O via RS485 multidrop using WIBNetTM exception reporting protocol.
  • Serial I/O multiplexer - connect 115S units to form a serial multi-drop I/O system using WIBNetTM exception reporting protocol: no Master device required (up to 32 serial addresses per multi-drop link).

  • Minimum configurable 8 (115S-11 has 16) digital I/O channels: each channel can be used as a volt free contact input or FET output (30VDC, 0.2A maximum).
  • The first four digital inputs on the 115S-11 can function as a pulse input (max pulse rate 1KHz). All digital outputs can function as a pulse output (max 100Hz).
  • Pulse inputs provide both totalized count and pulse rate as separate values.
  • Analog outputs selectable as single-terminal source or sink outputs with configurable current (4-20mA) or voltage (0-10) options.
  • Diagnostics including display I/O inputs and/or force I/O outputs and monitoring and confirming of communications.
  • Class I Div 2 hazardous areas approval.
