The DR4088RB is a feedback module designed for the Roco™ MultiZentrale-Pro™, Z21™ (black), z21™ (white) and is compatible with the Roco™ 10787. The DR4088RB is available in two versions: the OPTO and CS.
The OPTO version is 100% compatible with the Roco™ 10787 and can therefore be connected in exactly the same way. This version is usually used where reed contacts or Roco™ switching rails are used.
