Digital output modules P- or N-switching; shortcircuit-proof; up to 3-wire + FE
The module electronics supply the connected actuators
from the output current path (UOUT).
Digital output modules are available in the following
variants: 4 DO, 8 DO with 2- and 3-wire technology,
16 DO with or without PLC interface connection. They
are mainly used for the incorporation of decentralised
actuators. All outputs are designed for DC-13
actuators acc. to DIN EN 60947-5-1 and IEC 61131-2
specifications. As with the digital input modules,
frequencies of up to 1 kHz are possible. Protection of the
outputs ensures maximum system safety. This consists
of an automatic restart following a short-circuit. Clearly
visible LEDs signal the status of the entire module as well
as the status of individual channels.
In addition to the standard applications of the digital
output modules, the range also includes special variants
such as the 4RO-SSR module for rapidly switching
applications. Fitted with solid state technology, 0.5 A
is available here to each output. Furthermore, there
is also the 4RO-CO relay module for power-intensive
applications. It equipped with four CO contacts, optimised
for a switching voltage of 255 V UC and designed for a
switching current of 5 A.

Potential-distribution modules; system accessory
A wide range of accessory modules is available
for individual requirements of machine and plant
engineering. Various potential distribution modules
are available for the supply of sensors with 2- to 4-wire
connection technology directly from the remote I/O
system. These offer 16 "PUSH IN" potential points and
supply your application with any auxiliary potential
available. An empty module, where the system bus and
voltage supply are looped through, allows you to plan
expansion slots in a system and to start these up without
any interruptions if required.
