1.4 Non-reactive Bus Terminals

Note

Use of non-reactive Bus Terminals in safety applications

If a Bus Terminal is described as non-reactive, this means that the downstream terminal

behaves passively in a safety application (e.g. in the case of the all-pole switch-off of a po-

tential group).

In this case the terminals do not represent an active part of the safety controller and do not

affect the Safety Integrity Level (SIL) or Performance Level (PL) attained in the safety appli-

cation.

For details, please refer to chapter 2.17f in the TwinSAFE application manual.

Attention

Pay attention to the hardware version

Please pay attention to the information about the hardware version and non-reactivity of the

respective Bus Terminal in the chapters "Technical Data" or "Firmware Compatibility"!

Only terminals with the appropriate hardware version may be used without the attained SIL/

PL being affected!

HD Bus Terminal, 16-channel digital output 24 V DC, 0.5 A, with diagnostics

The KL2819 Bus Terminal has 16 digital output channels for the switching of 24 V loads up to 0.5 A. The

integrated diagnostics can be evaluated by the controller and indicated by the LEDs. Overtemperature and

the lack of a voltage supply to the terminal are supplied as diagnostic information. Moreover, each of the

channels can signal e.g. a short circuit. The switching state and any error of the output are indicated by the

LED. Maintenance of the application is simplified by the diagnostic function. The power contacts are

connected through; reference ground of the outputs is the 0 V power contact. The outputs are electrically

isolated from the fieldbus side.

2.3 Overload protection

The maximum continuous output current per output is around 0.5 A.

When switching on lamp loads, high starting currents occur that are limited by the output circuit of the

terminals. This ensures that the upstream circuit breaker does not trip (see fig. Overload current limitation).

KL2819 - Introduction and technical data

KL281910 Version: 1.0.0

Fig.2: Overload current limitation

Fig.3: Schematic illustration of the thermal switch-off in case of overload

In case of a long-term overload and/or short-circuit, the output is protected by the thermal switch-off of the

channel.

The output circuit of the terminal limits the current. The terminal maintains this current until important self-

heating of the channel occurs.

On exceeding the upper temperature limit, the terminal switches the channel off.

The channel is switched on again after it has cooled down to below the lower temperature limit.

The output signal is clocked until the output is switched off by the controller or the short-circuit is eliminated

(see fig. Schematic illustration of the thermal switch-off in case of overload). The clock frequency depends

on the ambient temperature and the load of the other terminal channels. This overload cause the device

temperature to rise further.

If several channels are overloaded, this leads to a rapid increase in the device temperature. The overloaded

channels are switched off when the upper limit for the device temperature is exceeded. The channels are

only switched on again if the temperature falls below the lower limit values for both the device and the

channel. The non-overloaded channels continue operating properly.

When switching off inductive loads, high induction voltages result from interrupting the current too quickly.

These are limited by an integrated freewheeling diode to approx. -35 V. Since the current reduces only

slowly, a delayed switch-off can occur in many control applications. For example, a valve remains open for

many milliseconds. Switch-off times are realized that correspond, for instance, to the switch-on time of the

coil.
