EP1816-3008 - Signal connection
Digital inputs/outputs, 24 V
DC
: 25 pin SUB-D socket
The digital input modules EP100x acquire the binary control signals from the process level and transmit them
to the higher-level automation device.
The signal connection is made through a 25-pin sub-D socket.
The sensors are supplied from the control voltage U
s
. The load voltage U
p
is not used in the input module,
but may be connected in order to be relayed downstream.

Attention
Please note the special pin assignment of the EP1816-3008.
The pin assignment of the EP1816-3008 differs from the EP1816-0008!
The supply voltage and GND connections differ, which means that incorrect connection
could damage the end devices, if these are not short-circuit-proof.
