EP23x9-0021 - Introduction
16 digital inputs or outputs, 24 VDC
The EP23x9-0021 EtherCAT Box has 16 digital channels that can each be operated as inputs or outputs. It is not necessary to configure whether a channel (pin 2 and 4 of the M12) is to be used as input or output; the input circuit is permanently connected internally to the output driver, so that a set output is automatically displayed in the input process image.
The inputs of the EP2339-0021 have a filter of 3.0 ms.
The inputs of the EP2349-0021 have a filter of 10 µs.
The outputs handle load currents up to 0.5 A and are short-circuit-proof and protected against reverse polarity. The total current of all outputs is limited to 4 A.
The connected sensors are supplied by an internal, short-circuit-proof driver module with a total of 0.5 A for all sensors. The inputs and outputs are supplied via UP. The signal status is indicated by LEDs. The signals are connected via M12 connectors.
 | Supply of the connected sensors from UP, not from US In contrast to many other modules, the EP23x9-0021 EtherCAT Box supplies digital sensors from the UP peripheral voltage and not from the US control voltage! Nevertheless, an overload of the sensor supply (current > 0.5 A) is also indicated here by the illuminated red US LED. |
Notice | |
For shutdown in the event of a fault, do not supply sensors externally If the design of your installation is such that the power supply voltage UP is switched off in the event of a fault, you must not power the connected sensors externally, but only through EP23x9-0021! Otherwise, when the UP energy is switched off, EP23x9-0021 can continue to draw energy from the external sensor supply, and the outputs will not be switched off. |
