EP2338-000x, EP2338-100x - Introduction
EP2338-x001
EP2338-x002
8-channel digital combi, 24 VDC
The EP2338 EtherCAT Box has eight digital channels, each of which can be operated either as inputs or outputs. A configuration whether a channel 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 outputs can handle load currents up to 0.5 A, are short-circuit proof and protected against polarity reversal. The inputs have a filter constant of 10 µs (EP2338-0001, EP2338-0002) or 3 ms (EP2338-1001, EP2338-1002). The state of each signal is indicated by means of LEDs. The signals are connected either via M8 (EP2338-x001) or M12 connectors (EP2338-x002).
 | Supply of the connected sensors from UP, not from US Unlike many other modules, the EP2338-xxxx supply connected sensors from the peripheral voltage UP instead of the control voltage US. Nevertheless, an overload of the sensor 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 EP2338! Otherwise, when the Up energy is switched off, the EP2338 can continue to draw energy from the external sensor power supply, and the outputs will not be switched off. |
Notice | |
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.
