The L-IOB I/O Controller is a family of Input/Output programmable controllers featuring various I/O configurations. Based on LOYTEC’s 32-bit L-CORE platform, the L-IOB I/O Controllers provide first class performance and a wide area of applications.

The built-in PLC functionality makes the L-IOB I/O Controllers a good fit for various control applications in building automation. Tthe L-IOB I/O Controllers are programmed with L-LOGICAD in 61131-3. The same application libraries and application programs can be used on both platforms.

LonMark Models
The LIOB-FT I/O Controllers and LIOB-IP852 I/O Controllers communicate in the LONMARK sytem via network variables over TP/FT-10 or Ethernet/IP-852 respectively. They come with a freely configurable network variable interface and offer up to 256 address table entries.

LIOB-FT I/O Controller
LIOB-18x I/O Controllers are compact, programmable automation stations for LONMARK systems with physical inputs and outputs.

LonMark TP/FT-10 Channel
LIOB-18x I/O Controllers communicate via twisted pair over a TP/FT-10 channel in the LONMARK system. LIOB-18x I/O Controllers offer extended features such as local alarming (SNVT_alarm and SNVT_alarm_2) and local scheduling.

Local Operation and Override
The modules contain a 128x64 display with backlight showing device and data point information. A jog dial is used for local operation by navigating through detailed information on the display and for operating and overriding of data points.

The configuration of the L-IOB I/O Contollers is done with the L-INX Configuration Tool.
L-IOB Controllers provide removable, vibration-proofed terminal screws with a clamping yoke connection in a 5.08 mm raster for wiring. These terminals can accommodate diameters from 0.2–2.5 mm² (26–12 AWG).
