SA-380 Railway Signalling Datalogger
SA-380 Railway Signalling Datalogger (PDF 175Kb)
Datalogging is now a standard technique within railway signalling engineering for both safety and performance management purposes. However, many of the systems currently in use are based on old technology, and, whilst beneficial, do not offer the functionality and cost benefits that the industry requires for the future.
The SA380 has been developed specifically to meet these requirements. Specified functionally by signal engineers it is the ideal solution for level crossing, interlocking and bespoke monitoring applications.
Simplicity
All data acquisition cards and associated electronics are contained within one enclosure, resulting in a compact yet modular solution. The number of channels per installation is configurable depending on customer / site requirements.
Networking and data access
The SA380 is enabled with the global networking standard TCP/IP and features a built–in web server. It can be remotely accessed over Ethernet or a dial-up link.
Data storage
The SA380 uses a simple RAID system, duplicating data to both its internal storage and a removable CompactFlash card. This duplication enables the CompactFlash card to be removed and used in incident investigations without affecting data stored on the logger.
Cost savings
The deployment of the SA380 is the most cost-effective datalogging solution, from level crossing to major interlocking schemes. Key savings are offered from:
- Ease of installation
- Low maintenance
- Integration of UPS, modem, display and input cards
Recorded data can be accessed using a standard web browser. For advanced remote analysis and diagnostic features (such as slow moving point alarms or SPAD investigations), a software plug-in has been developed for the Balfour Beatty Rail AssetView system.
In addition, the SA380 has a touchscreen LCD to allow maintenance technicians to access data directly on site. This removes the need for an inconvenient laptop computer or separate handheld terminal.
Reliability
Contained within the unit is a fully functional Uninterruptible Power Supply giving six hours of battery backup in the case of mains failure.
Low power consumption means that no cooling fan is required, which in turn means there are no dust filters to clean or moving mechanical parts to fail. If maintenance is required, the entire unit can be removed simply by disconnecting the input leads and a mains plug.
Safety
The SA380 has been designed specifically to meet the stringent safety requirements of railway signalling applications. All digital and analogue input channels are opto-isolated to a minimum of 1kV.
Usability
The SA380 is easy to install and use, with all functionality integrated into one compact unit.
A breakout board is available to enable simple connection to signalling relays. It is designed to fit the standard bars found in relay rooms and location cases.
Both the logger and its configuration software have been designed with ease of use as top priority. The unit will begin logging straight out of the box as soon as it is switched on.
