Short description

The digital input module of the DI 2xx/x series enables the connection of 8 (DI 240/B) or 16 (DI 260/A) digital inputs. 

24 V DC control signals are captured by the digital inputs and transmitted galvanically isolated to the higher-level automation device. In addition, two digital inputs can be used as interrupt inputs.

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

couplers.

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 designed 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., hydraulic 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

Short description

The DM 27x/A series is a digital input/output module of the KeConnect C2 product line and enables the connection of 6 

or 8 digital inputs and 8 digital outputs. 24 V DC control signals are captured by the digital inputs and transmitted galvanically isolated to the higher-level automation device. In addition, two of the digital inputs can be used as interrupt inputs. 

The digital outputs switch the 24 V DC control signals of a CPU module galvanically isolated from the connected actuators. In addition to the short-circuit connection, outputs that cause short circuits can be switched off individually.

This module is attached directly to a CPU module or can be operated with all KEBA controls by means of a bus coupler.
