DCM 1271 data decoupling module for SIMATIC S7-1200

With the aid of the DCM 1271 data decoupling module, the AS-Interface network can also be supplied with 24 V DC or 30 V DC from a standard power supply unit and the transmission of data and power can be implemented on one cable.

The data decoupling unit DCM 1271 has the same type of enclosure as an S7‑1200 module and can therefore be perfectly combined with the AS‑i master CM 1243‑2.

The data decoupling unit DCM 1271 has no connection to the backplane bus of the SIMATIC S7‑1200 and is therefore not counted as a communication module for the calculation of the maximum configuration.

Features of the DCM 1271 data decoupling module
  • Design: S7‑1200, 30 mm wide, degree of protection IP20
  • Detachable terminals (included in delivery)
  • Single data decoupling
  • Supply of several AS-i networks with a single power supply unit
  • Operation with 24 V DC or 30 V DC, grounded or non-grounded
  • Current limitation at 4 A
  • Integrated ground-fault detection
  • Diagnostic LEDs for ground faults and overloads
  • Signaling contact for ground-fault detection
Ground-fault detection

The integrated ground fault detection functions with grounded and non-grounded power supply: The connection of negative pole and ground (upstream from the data decoupling module) customary with 24 V DC power supplies is permitted. A ground fault to the negative or positive pole on the AS-Interface network (behind the data decoupling module) is identified and signaled via LED and a transistor output.
