DS205 – I2C reverse loop module

IN TESTPHASE

Version 1.0

The DS205 – I2C reverse loop module has connections for track signal, section A, section M (middle) and section B. Sections A and B have current detection and the module acts as feedback decoder for these two sections. This module has 3 relays, for each section one relay. The connected Arduino needs to take care of controlling these relays depending on the feedback information received. It has the same pinout as the PCA9685 PWM module and can therefore be connected in the same way. For connecting this module to Loconet, the DS104 – Lnet I2C interface can be used. Starting from software version 0.91 the reverse loop functioning is included in the sketch so the module will only act as feedback decoder if necessary.

The DS205 – I2C reverse loop module is sold as do it yourself project containing PCB and all components.
