6.5. Connecting inductive loads
When connecting inductive loads (e.g. TELEX couplings, relays or other
accessories with coils), you should switch a free-wheeling diode (e.g.
1N400x) in parallel, in order to avoid damage at the output. Check to
connect the anode of the diode to the function output.
6.6. Connecting accessories via a relay
When you want to switch an accessory / accessories via the decoder,
which connection would lead to exceeding the maximum current at the
output or of the decoder, you can switch the accessories via a relay
(e.g. 1xUm 1A 12V, item no. 84-61010) and connect them directly to
the vehicle´s current collector. As described in the section "Connecting
inductive loads" you should switch a free-wheeling diode (e.g. 1N400x)
in parallel to the relay.
The current consumed by the relay depends on its type. The relay
named in the example needs approx. 100 mA.
