Digital Output Module EP-2634

Figure 72: Digital Output
Module EP-2634
The digital output module EP-2634 can control up to 4 discrete outputs each with a
maximum of 2 A. One discrete 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 (IOUT).
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:
