PPI5-DCC Points Position Indicator

About the Product

The Points Position Indicator (PPI) monitors the brief switching voltage applied to either of the two coils of a points motor and displays the last operation using coloured LEDs. These LEDs can be mounted on a route mimic or control panel to provide a clear visual indication of the most recent point movement.

By detecting the momentary positive operating voltage applied during switching, the PPI reliably records and displays the last selected direction without interfering with normal points motor operation.

Key Features

• Monitors the brief positive operating voltage across points motors when they are switched.
• Lights the corresponding LED on a control panel to show the last operation of each set of points.
• Supports monitoring of up to 8 sets of points.
• LED brightness is adjustable to suit different lighting conditions.
• No resistors are required, simplifying wiring and installation.
• Opto-isolated inputs accept voltages from +5V to +60V.
• All settings are automatically saved to memory when the power is switched off.

Electrical Specifications

• Requires a 12V DC power supply.
