Digital Output Module EP-2634
Connection Diagram EP-2634
The digital output module EP-2634 can control up to 4 descrete outputs each with a maximum of 2 A.
One descrete output can be connected to each connector in a 2-wire or 3-wire + FE connection. A
status LED is assigned to each channel. The outputs are supplied with power from the output current
path (I
).
OUT
Each channel can be switched between positive and negative switching. This allows, among other
things, a switch in rotational direction if an DC motor is connected between two outputs. For this
purpose, an output byte is reserved for the physical outputs, and each channel is assigned two bits in
this byte. The switching characteristics of each output are set in the low nibble of the byte. If a bit is
set, the corresponding channel has positive switching, if it is 0 then it has negative switching. The
outputs are switched in the high nibble. Example: If you write the value 185 decimal (1011 1001
binary) in the output byte, channel 1 is set to 24 V, channel 2 is set to GND, channel 3 is deactivated
and channel 4 is set to 24 V.
The module is protected against external voltages between 0 V and the operating voltage.
