Weight 89 g

Permissible temperature (operation) -25°C to +55°C

Permissible temperature (storage/transport) -25°C to +85°C

Permissible humidity (operation) 75% on average, 85% occasionally

Permissible humidity (storage/transport) 75% on average, 85% occasionally

Permissible air pressure (operation) 80 kPa to 106 kPa (up to 2000 m above sea level)

Permissible air pressure (storage/transport) 70 kPa to 106 kPa (up to 3000 m above sea level)

Degree of protection IP20 according to IEC 60529

Class of protection Class 3 according to VDE 0106, IEC 60536

In the range from - 25°Cto+ 55°C appropriate measures against increased humidity (> 85%) must be

taken.

For a short period, slight condensation may appear on the outside of the housing if, for example, the

terminal is brought into a closed room from a vehicle.

Limitation through software 63, maximum

Limitation through power supply unit

– Maximum current consumption of the connected local

bus modules at the communications power:

≤ 2 A DC

– Maximum current consumption of the connected local

bus modules at the analog supply:

max

≤ 0.5 A

The IBS IL 24 RB-LK does not count as an Inline station device (63, maximum).

Observe current consumption of the terminals

Observe the current consumption of each device when configuring an Inline station! It is specified in every

terminal-specific data sheet. The current consumption can differ depending on the individual terminal. The

permissible number of devices that can be connected therefore depends on the specific station structure.

Derating

Up to an ambient temperature of 55°C For this temperature range, insert at least one Inline

terminal that is not an INTERBUS device (e.g., segment/

power terminal without protocol chip) between bus coupler/

controller and the first IBS IL 24 RB-LK.

Electrical Isolation/Isolation of the Voltage Areas

Common Potentials

The 7.5 V communications power, 24 V analog supply, 24 V bus coupler supply, and 5 V communications power of the

branch terminal share a common potential.

Separate Potentials

The communications power ground is jumpered to the ground of the 7.5 V communications power for the bus coupler

power supply unit.

The I/O supply is always electrically isolated from the interface supplies.
