EP23x9-0021 - Introduction
16-channel digital combi, 24 VDC
The EtherCAT Box EP23x9-0021 has 16 digital channels, each of which can be configured as an input or an output. A configuration whether a channel (Pin 4 of M8 socket)is to be used as input or output is not required; the input circuit is internally permanently connected to the output driver so that a set output is automatically displayed in the input process image.
The inputs of EP2339-0021 have a filter of 3.0 ms.
The inputs of EP2349-0021 have a filter of 10 µs.
The outputs can handle load currents up to 0.5 A, are short-circuit proof and protected against polarity reversal. The sum current of all outputs is limited to 4 A.
The connected sensors are supplied via an internal, short-circuit proof driver module with a total of 0.5 A for all sensors. The inputs and outputs are supplied from UP. The signal state is displayed by LEDs; the signal connection is established via screw-type M8 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 power supply (current > 0.5 A) is indicated by the LED US lighting up red. |
Notice | |
For shutdown in the event of a fault, do not supply sensors externally If the design of your installation is such that the supply voltage Up is switched off in the event of a fault, you must not power the connected sensors externally, but only through the EP23x9-0021! Otherwise, when the Up energy is switched off, the EP23x9-0021 can continue to draw energy from the external sensor power supply, and the outputs will not be switched off! |

Damage to sensitive signal transducers due to current peaks The protective circuit of a digital input can cause an inrush current peak of well over 2 mA during the switching operation. This current spike can damage sensitive signal transducers such as reed switches.
