Index

The LIOB-45x Modules are LonMark certified and communicate over Ethernet/IP-852 in the LonMark System. They provide up to 512 address table entries (ECS mode) which eliminates all binding restrictions.

LonMark IP-852 Channel over Ethernet

The LIOB-45x I/O Modules are equipped with two Ethernet ports including a built-in Ethernet switch. This allows for building a daisy chained line topology of up to 20 devices, which reduces costs for network installation. Dual Ethernet port devices also allow the setup of a redundant Ethernet installation (ring topology), which increases reliability. The redundant Ethernet topology is enabled by the Rapid Spanning Tree Protocol (RSTP), which is supported by most managed switches.

The LIOB-45x Modules are equipped with a Web interface to query the device status. The local display can be accessed via VNC.

LIOB-IP Mode

The LIOB‑45x Modules can be switched to LIOB‑IP mode using manual local operation. In LIOB‑IP mode, the LIOB‑45x Modules extend L‑INX Automation Servers, L‑ROC Room Controllers, L-IOB I/ O Controllers and LIOB-AIR I/ O Controllers with physical inputs and outputs via plug and play.

Local Operation and Override

All L-IOB I/O Modules are equipped with an LCD display (128x64) with backlight and jog dial for manual local operation. Device and data point information is displayed in text form and via graphical symbols.

General Input and Output Specification of LOYTEC devices

UI Universal Input

UIs are universal inputs for four different input types. They have an input voltage range of 0 V to 10 V, and can withstand up to 30 V. The UIs correspond to class 1 with a relative accuracy of ±1 % (of measured value) between 1 V and 10 V, and an absolute accuracy of ±10 mV between 0 V and 1 V. The ADC resolution is 16 bits. Galvanically isolated sensors resp. switches must be connected. Universal inputs can be configured as:

  • Binary Input (Digital Input)

    Input impedance > 20 kΩ, sampling period 10 ms.
    • In voltage mode, the threshold values are < 0.8 V for low level and > 2 V for high level.
    • In resistance mode, the threshold values are < 1.9 kΩ for low level and > 6.7 kΩ for high level.
    Between the threshold values, the resulting level of the UI is not defined.
  • Voltage Metering 0-10 V

    Input Impedance > 20 kΩ, sampling period < 1 s.
  • Current loop 4-20 mA

    Input Impedance > 20 kΩ, sampling period < 1 s. An internal shunt of 249 Ω is available for some universal inputs. Otherwise, an external resistor of 249 Ω must be used as a shunt.
  • Resistance Measurement

    Input Impedance 10 kΩ, sampling period < 1 s. Resistors in the range of 1 kΩ to 100 kΩ can be measured. For popular temperature sensors (e.g. Pt1000, NTC10K, NTC1K8, Ni1000) fixed internal translation tables are provided. For all other temperature sensors, translation tables can be defined in the configuration tool and used on the device.

The average sampling period p of analog inputs depends on the number of active (non-disabled) universal inputs n that are configured in analog mode. The formula for p is:

p = n * 125 ms

This means if e.g. only two UIs are configured as analog inputs, a new sample is taken every 250 ms (on average) for each of the two inputs. The UIs configured as digital inputs are unaffected (sampling period always 10 ms) by this formula.

DI – Digital Input, Counter Input (S0-Pulse)

DIs are fast binary inputs, which can also be used as counter inputs (S0). They follow the S0 specification for electric meters and have a sampling rate of 10 ms. They change state at a load of 195 Ω between the DI terminal and GND. Galvanically isolated sensors resp. switches must be connected.

AO – Analog Output

AOs are analog outputs with a signal range of 0 to 10 V (up to 12 V), a resolution of 10 bits, and a maximum output current of 10 mA (20 mA @ 12 V), short circuit proof (2 outputs at a time). The accuracy over the whole range is ±100 mV.

DO – Digital Output

The following digital outputs are available:

  • Relay 6A Output: Switching capacity 6A, 250VAC resp. 30VDC. Max in-rush current 6A, max. 600W (resistive) @ 250VAC.
  • Relay 10A Output: Switching capacity 10A, 250VAC resp. 30VDC. Max in-rush current 10A, max. 1600W (resistive) @ 250VAC.
  • Relay 16A Output: Switching capacity 16A, 250VAC resp. 30VDC. Max in-rush current 80A, max. 2000W (resistive) @ 250VAC.
  • TRIAC Output: Switching capacity 0.5A, 24 to 230VAC. External relays must not be connected.

When switching higher loads than specified an interface relay must be used and a quenching circuit like a varistor or RC element must be used at the selected LOYTEC device.

PRESS – Pressure Sensor

These inputs represent differential pressure sensors. They are equipped with two 3/16” (4.8 mm) hose connectors.
