Relays for BACC
The HR, DR, TR and CT series relays are specifically designed for BACC Wayside applications on railway lines, ensuring high levels of operational safety, intrinsic reliability and interoperability with Westinghouse and Sasib systems used in Italian railway infrastructure.
These devices integrate advanced electronic technologies with electromechanical components certified in accordance with the railway regulations and specifications, ensuring:
- Intrinsic safety
- High contact reliability
- Wide operating temperature range
- Mechanical and electrical compatibility with existing equipment
- Protection against overvoltage and contact bounce
- Ease of replacement and maintenance
The Electronic HR relay is produced in two versions: one for B.A. WESTINGHOUSE and one for B.A. SASIB. It is an electronic device that combines intrinsically safe electronic circuits with highly reliable relays (compliant with RFI TCSSTB SF IS 21 756 A)

The Electronic TR is produced in two versions: one for B.A. WESTINGHOUSE and one for B.A. SASIB.
This fully electronic device features bounce-free, overvoltage protected output contacts.
Technical features
Electronic TR for B.A. Westinghouse
This fully electronic device is available in two versions and is entirely interchangeable with the corresponding versions it replaces.
It is secured to the counterplate by means of a snap-on device. To remove it, pull firmly (approximately 5 kg of force). The mechanical coding is identical to that of the model to be replaced. The negative terminal of the Electronic TR must be connected to the negative terminal of the GA12F control unit. A pair of red/green LEDs flashing in code indicates correct TR operation.
