ZEPIC5 (1)_editedThe ZEPIC5-DTC represents a major technological advancement in Distance to Couple systems for railroad classification yards. The system employs proprietary signal processing algorithms used for frequency to distance conversation, speed calculation and determination of direction. The system provides isolated RS485 communication (half or full duplex) to interface to yard computers allowing for remote access of all internally processed data.

System provides improved distance measurement accuracy and increased track fill levels.

Provides distance to couple, speed and direction data.

One unit monitors 2 track circuits.

Isolated RS-485 communications. User configurable unit ID, half or full duplex.

Self-contained unit provides all necessary data processing, track drive and communications.

Diagnostic troubleshooting codes with built-in push buttons and display.

All user configurations stored in non-volatile memory.

9 – 30VDC operation.

Secondary surge protection built in.

Water and dust resistant enclosure. (9.5” x 6.25” x 4”)

ZEPIC5-DTC is available as individual unit or as a fully assembled tested system.

Z3 Plus

Z3_editedZ3 Plus, 2-wire Audio Overlay Presence Detector

The Z3-Plus is a 2-Wire audio overlay track circuit operating on 9 to 24VDC and is field configurable for the following track drive frequencies: 8.2K, 10K, 11.5K, 13.2K, 15K, 17.5K, 20K, 26KHz. This track circuit provides a sinusoidal output under all track load conditions minimizing possible harmonic interaction with other audio equipment on the track. The unit also provides consistent activation point independent of operating battery. Digital receiver circuitry provides for precise receiver operation. The unit is calibrated by simply dropping a shunt at the activation point and pushing the cal button. Additionally, a non-vital loss of shunt timer is provided to further optimize consistent performance. An LED has been provided to allow a visual indication of the Z3-Plus relay drive.

Ideal for applications including AEI, HBD, DED and switch unlock.

Provides track frequencies of 8.2KHz, 10 KHz, 13.2 KHz, 17.5 KHz, 20 KHz, 26 KHz.

Reduces spare inventory by providing the most common track frequencies in single field configurable unit.

N.O. and N.C. dry contact presence output simplifies interface to wayside equipment.

Simple “drop a shunt and press a button” calibration process.

2 second Loss of Shunt timer built-in.

9 – 30 VDC operation.

Secondary surge protection built-in.

Water and dust resistant enclosure. (8″ x 4.75″ x 2.5″)
