Connection

Before commissioning in TwinCAT, connect the terminal as follows:

  1. Supply the EL2574 via the power contacts with 24 VDC.
  2. Connect the data line (and clock line) to the appropriate terminal points.
  3. Connect the LED supply via the terminal or directly to the LEDs (see note from chapter "Supply of the connected LEDs"). Note here that the terminal only serves as a rail.

Connection instructions

  • Make sure that the supply of the LED has the same 0 V potential as the 0 V power contact, as this is the reference ground of the terminal. The 0 V power contact is also internally connected to terminal points GND.
  • Shielded cables are mandatory for connecting the LED.
  • For stable data transmission, the data and supply lines for the LED should be kept as short as possible and should not be routed past switching elements.
