Short description

Digital output modules DO 242/B and DO 272/A enable the connection of up to 14 digital outputs. The digital outputs

switch the 24 V DC control signals of a central module galvanically isolated from the connected actuators and are desi

gned for a load of up to 2 A at 50 % simultaneity.

The modules are equipped with a fast shutdown function that enables a rapid shutdown of inductive loads, e.g., hydrau

lic valves. Machine processes can thereby be accelerated and productivity increased.

The operational safety is ensured by the permanent short-circuit protection of the outputs. Should a short circuit occur,

it is detected and reported to the control module.

These modules are attached directly to a CPU module or can be operated with all KEBA controls by means of bus

couplers.
