Safety Sensor Interface provides intelligent control outputs.
Press Release Summary:
Supporting interconnection of up to 10 safety sensors to 1 sensor input of safety controller unit, Intelligent Input Expansion Unit provides capacity for up to 40 sensors. Intelligence in form of control outputs allows each error to be detected with additional monitoring method, even when series connection is applied. With electronic monitoring of individual channels, machine can achieve performance level "d" in accordance with safety standard EN ISO 13849-1.
Original Press Release:
Intelligent Input Expansion Units
To ensure the safety of machines and systems, moveable guards such as doors and flaps are monitored with special safety sensors. To avoid having to wire them individually, interfaces or input expansion units are used in which the sensors are connected in series and plugged into the safety controller unit via a single cable. In common interfaces, however, all errors cannot be detected when this cascading process is utilized – which is why the machine can no longer achieve performance level "d" in accordance with safety standard EN ISO 13849-1.
For this reason, elobau has equipped the existing interfaces with "intelligence" in the form of control outputs. This allows each error to be detected with an additional monitoring method even when series connection is applied. Thanks to the electronic monitoring of individual channels, which is possible with the new elobau interface even without the use of a standard PLC, performance level "d" can still be reached. The costs of the new interface and the additional measures are negligible compared to wiring the sensors individually.
The new interface enables the interconnection of up to ten safety sensors to one sensor input of the safety controller unit, which thereby offers the capacity for up to 40 sensors.
If you are interested, contact elobau for full details on these and other controls, sensors and machine safety products.
