ESU SwitchPilot Extension, 4x relay output – item 51801

If necessary, the SwitchPilot can be supplemented with the SwitchPilot Extension module: Docked to the side of the SwitchPilot, it offers 4 relay outputs for switching potential-free consumers or for core polarization.

Operating modes

The SwitchPilot Extension Module only works in conjunction with a SwitchPilot. Plugged in on the side, it is supplied with power directly from the SwitchPilot. It contains a total of 4 double relays (2 x UM), each of which is assigned to a transistor output pair of the SwitchPilot. The position of the respective relay depends directly on the switching status of this output pair.

With the help of the relay, consumers can either be switched galvanically isolated from the rest of the rail circuit (function analogous to k84) or a motorized switch drive can be reversed.

Since each relay can carry up to 1.5A continuous current, it can be used not only to polarize switch frogs, but also to supply block sections with voltage depending on the signal or to switch motor drives such as (water) pumps.

The option to control motorized switch drives is particularly tricky: the SwitchPilot Extension module can of course also handle the motor polarity reversal required for this.
