Connections

The module has screw terminals for all its external connections.

The train sensor connects to the A, GND, and C terminals.

The DONE and TRIG terminals are for connection to adjacent modules.  The TRIG
input is activated when connected to GND, by a switch, push button or other
module.  Note the push-button on the module connects the TRIG terminal to GND
and so can be used to trigger the module.  This terminal must not be grounded at the
time the module is powered, otherwise it will enter programming mode (see later).

The power input is designed for 12V DC. Reverse polarity will not damage the
module, although the module will not function.

The current drawn is 50mA when one relay is energised, 100mA when both relays
are energised, and 10mA when no relays are energised.

The relay output terminals are each rated at up to 1A at 24V DC.
