PPI4-DC Points Position Indicator

About the Product

The Points Position Indicator (PPI) monitors the brief switching voltage applied to points motors and displays the last operation using coloured LEDs. It is ideal for use on route mimics and control panels, providing a clear visual indication of point positions without affecting normal motor operation.

The PPI detects the momentary positive operating voltage across either coil of a points motor and records the last switching direction, allowing operators to see the current route status at a glance.

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 +25V.
• All settings are automatically saved to memory when power is switched off.

Electrical Specifications

• Requires a 12V DC power supply.
