Control unit allows flexibility of parameter selection for inputs, outputs

The new “eloFlex” system from elobau has been designed for the flexibility of parameter selection for logic control of sensor inputs and relay outputs. The user can choose between normally-open/normally-open sensors and emergency-stop types, as well as the normally-open/normally-closed input type.

The new “eloFlex” system from elobau has been designed for the flexibility of parameter selection for logic control of sensor inputs and relay outputs. This means the type of sensor can be freely chosen for each of the four inputs on the control unit. The user can choose between normally-open/normally-open sensors and emergency-stop types, as well as the normally-open/normally-closed input type. In the latter case, the order in which the two contacts are actuated is not taken into account. In addition, operation as two-hand safety control can be selected for two-sensor inputs. The monitoring of 24 V PNP outputs, such as is standard for safety light curtains, is also possible.

The control unit has four outputs where one or more of the four input sensors can be assigned via a freely selectable logic gate (AND, OR, NAND, NOR, XOR and XNOR). A delay time of between 0 and 99.9 seconds can be set in 100-ms steps for each safety output. In addition, there is an output for error messages available that can be linked to an SPLC (as an example). Separate inputs are available for monitoring external gates. elobau provides the programming and validation of the required configuration and then tests the functionality of the safety evaluation unit using a special test program. This saves valuable configuration and test programming time/cost for the end user. In addition, each unit is very clearly identified by a unique part number that identifies the specific programming contained.

There is a choice of SIL 2 and SIL 3 (Safety Integrity Levels in accordance with EN 62061) for all types. UL/ETL approval is available.
