Product Description:
The DKC04.3-LK-ITB01 is an interface card manufactured by Bosch Rexroth Indramat as part of the DKC Drive Controllers series. Classified under the EcoDrive product type, this card permits the associated controller to exchange serial drive data with external automation devices. By routing transmit and receive pairs through dedicated connectors, it simplifies integration of feedback, diagnostic, and reset signals so the drive can coordinate motion axes, monitor status, and respond to higher-level control sequences inside industrial production equipment.
Design 3 of the card supplies two independent communication channels, and the card has 2 connectors. The first channel is brought in through a D-SUB 9 (Male) plug that carries the incoming data pair DO1,/DO1 In and DI1,/DI1 Out. Outgoing data are passed forward on a D-SUB 9 (Female) socket that exposes the pair DO2,/DO2 Out and DI2,/DI2 In, enabling daisy-chain wiring to the next module. Diagnostic LEDs labeled H40–H45 report link health, frame activity, and error states without external test gear. All signal lines can be landed with individual wires sized between 0.08–0.5 mm², while a peripheral shield connection is established directly to the metal housing to maintain EMC compliance.
The interface option code 04 identifies the logic needed to work with DKC controllers that deliver or absorb peak currents of 40 A, 100 A, 200 A. For auxiliary electronics, terminal X41 provides a stabilized +5 V output, and a complementary /RBST line on the same header offers a reset input for remote restart commands. Continuous cable shielding is achieved via the metal housing, which helps prevent ground loops when multiple EcoDrive units share the same enclosure. This layout supports multi-axis drive installations and keeps serial wiring organized inside a shared control cabinet.
