Allows Greater Substation Control!
The L-PRO Line Protection Relay is now available with expanded I/O (4U rack-mount enclosure with an optional I/O board). The L-PRO now contains up to 20 programmable external inputs (9 inputs standard).

External dc voltages of either 48/125 volts or 125/250 volts are possible depending on the range provided. The expanded L-PRO contains 21 output relay contacts (14 outputs standard). Each contact is programmable & has its own breaker trip capability. All output contacts are isolated from each other. The output contacts are closed for a minimum of 100 ms after operation.

The standard L-PRO relay is 3 rack units (5.25 inches high), while the L-PRO with extended I/O is 4 rack units (7.0 inches high). Both are approximately 12.25 inches deep & are designed for a 19-inch rack.
