The controller unit evaluates the signals of machine safety applications in machines and plants.

With the arbitrarily configurable structure, the inputs can be used for a wide range of functions,

for example as protective door monitoring, emergency stop, or to connect light curtains. A 2-hand

control can also be implemented.

+ SIL 2 or 3 (EN IEC 61508) SILCL 2 or 3 (EN IEC 62061), PL d or e (EN ISO 13849-1) and ETL approval

+ for sensors with 2 N.O. contacts and also suitable for N.O./N.C. contacts

+ sensor inputs also suitable for OSSD (Output Signal Switching Device) (e.g. light curtains)

+ up to four independently switching safety outputs

+ time and cost savings through pre-configured and validated units, which also facilitates easy integration

+ unique identification of the configuration via permanently assigned part number + emergency stop function

Options

Safety controller unit eloFlex 471EFR... flexible configuration of the inputs and outputs

The internal logic combination of the safety inputs and outputs with AND, OR, NAND, NOR, XOR,

XNOR permits a high adaptability to the application. The safety outputs can be switched on and off

with a delay of 0.1 to 99.9 s (resolution 0.1 s). Motor contactor auxiliary contacts or an additional

start button can be used for external monitoring. The control outputs of the eloFlex unit can also

be configured. The SILCL 3 / PL e option can be offered at very reasonable cost due to the number

of the safety outputs.
