M12X0-00X | Lightbus interface modules


The M1200 is a Lightbus interface card for the integration of customer-specific electronics into the Lightbus system. The M1210 interface module features an integrated 24 V DC/5 V DC switched/mode power supply and a card carrier for simple installation. 32 parallel data inputs/outputs, four “fast” interrupts, and interface control signals permit easy adaptation to a wide variety of applications.


  • integration of all digital functions into a single LCA (Logic Cell Array) circuit
  • communication protocol optimised for 32 bit data transfer
  • designed as piggyback card with 2 x 34-pin connector
  • fast data transmission from PC, PLC or CNC to application-specific circuitry
  • integration of additional application-specific functions into the LCA communications IC, including, for example, counters or bus int
  • erface (up to 6,000 equivalent gates)
  • easy integration of the customer’s own devices into the Lightbus System
  • microprocessor bus interfaces available for Intel® and Motorola processors
