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.
