1. General
1.1. Various Subassembly Designs/Indexes
Subassemblies from Index D onwards are a compatible further development. You can see this by the three
additional LEDs at the top edge of the subassembly.
This description applies to both designs. The differences are described in the appropriate topics.
Subassemblies with Index C were never delivered.
1.2. Brief Description
• The IPS.LBA-1 (INTERBUS-Based Press I/O System . Loop Bus Adapter - Type 1) is an INTERBUS
remote bus node (bus terminal) and is for linking an INTERBUS loop spur.
• Localizes interruptions in the connected loop spur.
• The INTERBUS IN and OUT remote bus interfaces are executed in two-wire technology (9-pin Sub-D)
in accordance with the Interbus specification.
• Separate supply feed for loop and bus terminal logic, which are also galvanically isolated but can be
connected externally.
• integrated mains unit for the I/O subassemblies that are connected to the loop – supplies 28.5 V DC.
• Functions only in I
• Diagnostics LEDs for the status of the INTERBUS and supply voltages
• No need to set DIL switches or jumpers
• ID code: 4 (04 hex)
• Number of data words: 0
• MAN Item Number: 16.86958-0022
NTERBUS systems that are controlled by master firmware of Version G4 and above
1.3. Important Note!
When using this subassembly you must also use the general system description (Item No.:
T16.86902-0016) and the "Allgemeine Information - Interbus-Loop" [General Information on Interbus
Loop](Item No.:T16.86902-0028)! This contains guides to configuration, assembly, commissioning
and servicing.
When configuring the loop, you must observe the permissible line lengths, the maximum loop current (1.8A)
and the voltage drop in the loop!
For optimum functioning of the loop equipment, e.g. the brightness of bulbs, a voltage must be available at
every location in the loop of between 23.5V and 30.0V DC.
Bus operation (cyclical data traffic) is guaranteed from 15.5V.

You connect the Interbus loop spur via this terminal block. The jumper between pins 9 and 10 is necessary
to be able to detect a connected loop.

carries out electronic loop detection by monitoring the loop voltage.
