RSN 2021 Exhibitor – Sella Controls provide PLC controller based Level Crossing Trial

SELLA CONTROLS has received an order from Amey Rail Signalling & Systems for a trial of a safety PLC controller based Level Crossing.

 

SELLA CONTROLS and Amey Rail have been developing a COTS Safety PLC based Level Crossing solution for 4+ years based on a range of safety PLCs. Using standard proven industry safety PLCs in Level Crossings and railway signalling is a logical step and has been done by railway administrations in other countries.

 

The main advantages are significant cost reductions and increased system performance. Use of Safety PLCs simplifies the design and testing. PLCs have significant design tools to simplify the design process and further reduce costs. The function block logic used in PLCs is easily suited and understood by signalling engineers.

Amey Rail and SELLA CONTROLS have produced the Generic Application Safety Case (GASC) for the introduction of a safety PLC into the UK and the Specific Application Safety Case (SASC) for application to Network Rail level crossing work.

The purpose of the trial site is to gain Network Rail Product Acceptance which will then allow us to supply our control system to Network Rail and Tier one contractors which will be used to upgrade outdated relay-based level crossing systems over the coming years.
