EP2339-0042 - Introduction
16-channel digital input or output 24 V DC
The EP2339-0042 EtherCAT Box has 16 digital channels, each of which can optionally be operated as an input or as an output. A configuration for using a channel as input or output is not necessary; the input circuit is internally connected to the output driver, so that a set output is displayed automatically in the input process image.
A filter constant of 3.0 ms is available for the inputs. The outputs are short-circuit proof. They handle load currents of up to 0.5 A each. The state of each signal is indicated by means of light emitting diodes. The signals are connected via M12 screw type connectors.
The EP2339-0042 is interference-free. You can use the EP2339-0042 instead of an interference-free standard terminal in accordance with the following chapters of the TwinSAFE Application Guide:
- "All-pole disconnection of a potential group with downstream interference-free standard terminals (Category 4, PL e)"
- "Single-pole disconnection of a potential group with downstream interference-free standard terminals with fault exclusion (Category 4, PL e)"
- „EL2911 potential group with interference-free standard terminals (Category 4, PL e)"
 | Supply of the connected sensors from UP, not from US In contrast to many other modules, the EP2339-0042 EtherCAT Box supplies digital sensors from the UP peripheral voltage and not from the US control voltage. |
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 the EP2339-0042! Otherwise, when the UP energy is switched off, the EP2339-0042 can continue to draw energy from the external sensor supply, and the outputs will not be switched off. |
