Description

The Points Position Indicator (PPI) monitors the brief switching voltage to either of the two coils of a points motor, and displays the last operation using coloured leds that can be mounted on a route mimic.

• Monitors the brief positive operating voltage across points motors when they are switched
• Lights a corresponding led on a control panel to show the last operation of each set of points
• Saves all settings automatically to memory when the power is switched off
• Monitors up to 8 sets of points
• Adjustable led brightness
• No resistors are required simplifying wiring
• Opto-isolated inputs accept voltages from +5V to +25V
• Requires a 12V DC Power Supply
