115S Features:

Selectable communications protocol - Modbus (RTU and ASCII) or WIBNet (exception reporting, peer to peer with security encryption).

Three I/O versions available:

Each model has 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)

Each DIO channel can function as a pulse output to a maximum 15Hz with the first four DIO/pulse input channels on the 115S-11 to a maximum pulse rate of 1KHz. Pulse inputs provide both totalized count and pulse rate as separate values.

Configurable analog inputs - 0-20/4-20mA: 0-10V. Selectable as 8 single terminal inputs (commoned) or 4 dual terminal 'floating' inputs (115S-12).

Analog outputs are commoned with selectable 'supply' or 'sink' connections (115S-13).

Each analog input has a high/low set point to determine a set-point status.

Field test and display I/O inputs and/or force outputs, monitor and confirm communications and configure units with user friendly configuration software.
