2.1 Prerequisites for Operating the Remote I/O Unit
2.2 Introduction
Remote I/O stations are signal modification devices that act as an interface for signals between
field devices and process control systems. The individual components, i.e., the I/O modules,
com units, and power supplies, are plugged into the slots on the backplane. Com units are
available for various standard buses and form the interface between the I/O modules and the
process control system. Power supplies are used to power the I/O modules and com units.
The bus systems detailed below are supported.
This manual sets out how to work with the hardware. For information on how to configure the
com units and I/O modules, refer to the software manual for the relevant com unit in use.
Note!

The LB remote I/O system must only be installed and operated if installed in a surrounding
enclosure
that complies with the requirements for surrounding enclosures in accordance with
IEC/EN 60079-0 and that
is designed with IP54 protection in accordance with IEC/EN 60529.
Note!
Requirements for Non-Hazardous Areas
The LB remote I/O system must only be installed and operated if installed in a surrounding
enclosure
that complies with the requirements for surrounding enclosures in accordance with
IEC/EN 60079-0 and that
is designed with IP54 protection in accordance with IEC/EN 60529.
Alternatively, installation and operation of the system is permitted in a controlled environment
where pollution degree 2 in accordance with IEC/EN 60664-1 is ensured.

2.4.1 Function
Backplanes are used to hold com units, power supplies, and I/O modules. Fixed slots are
reserved on the backplane for com units and power supplies. Slots for I/O modules have equal
status, meaning functions can be arranged side by side as required.

2.4.4 Backplane and Module Compatibility
In principle, LB backplanes are compatible with all LB modules. Single-width I/O modules
occupy one slot, while double-width I/O modules occupy two slots. However, please be aware
of the following restrictions.
Temporary Overload of the Power Supply
To avoid an overload of the power supply in the startup phase as a result of increased startup
currents, the number of certain I/O modules on the backplane is limited.
Use:
A maximum of 11 LB3*, LB4*, and LB7* single-channel I/O modules.
Each of these I/O modules consumes 9.09 % of the startup capacity.
Or a maximum of 8 LB3*and LB7* four-channel I/O modules.
Each of these I/O modules consumes 12.5 % of the startup capacity.
LB9035A
Only use this backplane with the following I/O modules:
Digital input: LB1*08*
Digital output: LB6005*, LB6006*, LB6*08*, LB6*10* ... LB6*15*
Analog input: LB3*05*, LB5*04*, LB5*05*
Analog output: LB4*05*
2.4.5 Scope of Delivery
Base backplanes are not delivered with any accessories.
Extension backplanes are delivered with a 1-m-long double-ended cordset (LB9140A). The
double-ended cordset establishes the connection to the base backplane.
2.5 I/O Modules, Com Units, and Power Supplies
2.5.1 Function
I/O modules are signal conditioning devices. Field signals from a hazardous area are
conditioned for controllers or process control systems in a safe area. The slots for the I/O
modules on the backplane have equal status, meaning functions can be arranged side by side
as required.
Com units form the interface between the I/O modules and the process control system. A com
unit can control up to 46 I/O modules and transfer their signals across various standard buses.
The com unit converts the protocol of the bus integrated in the backplane to the protocol of the
higher-level bus system.
Power supplies provide power to the I/O modules and the associated com units on a
backplane. The slots for com units are mechanically coded on the backplane and marked
accordingly.

LB Remote I/O System
Product Specifications
2.5.2 Design and Dimensions
Both single-width and dual-width modules are available. Com units and power supplies are
always dual-width. I/O modules are single-width or dual-width depending on the model.
Both the I/O modules and the com units and power supplies are equipped with LEDs on the
front that display the device status.
The I/O modules have connections on the front to which the relevant field devices are
connected.

2.6.2 Field Wiring
The following accessories are available for field wiring.
Terminal Blocks
Terminal blocks are wired to the field devices, attached to the front sockets of the I/O modules,
and tightened using the side screws. Terminal blocks can come in the form of screw terminals,
front screw terminals, or spring terminals. All versions are available in green and blue. Use
green terminal blocks for non-intrinsically safe circuits and blue terminal blocks for intrinsically
safe circuits.
Screw terminals

Protective covers are used to protect the wiring to the terminal blocks, so that no bare
conductive parts are exposed. Protective covers are available in green and blue. Use green
protective covers for non-intrinsically safe circuits and blue protective covers for intrinsically
safe circuits.

Cold Junctions
Cold junctions have a prewired Pt100 thermocouple on plug openings 1 and 2 for numerically
correcting the thermoelectric voltage. Cold junctions are available in green and blue. Use
green cold junctions for non-intrinsically safe circuits and blue cold junctions for intrinsically
safe circuits.

Coding Pins
Coding pins provide a unique assignment between I/O modules and terminal blocks or the
associated field devices. To do this, the coding pins are pushed into the grooves provided in
the front sockets of the I/O modules. This prevents terminal blocks from being accidentally
plugged into another I/O module.
Coding pins

Watchdog Plugs
The watchdog plug is used with digital outputs with a feedback input (LB2101A ... LB2113E).
The watchdog plug sends the output signal from the I/O module back to its input channel,
making it possible to check the function of the I/O module, as well as the communication
between the process control system and the I/O module.
Figure 2.24 Block diagram for the LB9180A
Resistor Network
If binary I/O modules are used, for example with a mechanical contact, an additional resistor
network must be installed to ensure that the line fault detection function can work correctly.
Using the additional resistor network, the electronics can distinguish between a closed switch
and a short circuit.

2.6.3 Separation between Intrinsically Safe and Non-Intrinsically Safe I/O
Modules
The separation wall is attached to the backplane between I/O modules with intrinsically safe
circuits and I/O modules with non-intrinsically safe circuits to ensure a clearance of 50 mm
between intrinsically safe circuits and other circuits. The separation wall can be installed on
both backplanes with and without a label carrier.
