Relays Module for LocoIO

This is a Relay module for LocoIO. Then it is possible with the LocoIO outputs (5V, max 20mA) to drive different items with higher voltages and bigger currents. Each Relay has a change-over switch. The module can be provided with 2 bi-stable, 4 mono stable relays or 1 bi-stable and 2 mono stable relays .

Some Applications:

• Current interruption on signals for analog layouts
• Polarization of the hart piece of the points
• Terminus loop circuit
• Turntable operation
