Lightning10-BTT (Preliminary)

Lightning10-BTT is a set of modular Front End modules dedicated to Blade Tip Timing applications. Conceptually the Lightning10-BTT is similar to the larger Lightning32-BTT unit but with fewer channels in a more compact form factor. The modules also use LEMO M-series connectors to provide better performance within high-vibration environments (design intent is DO160G Cat R Curve W) whilst retaining the same performance for the other environmental tests as the Lightning32-BTT.

Master Module - This module features:
- 8x Optical inputs (Laser + Photodiode)
- 2x Voltage inputs (for tachos)
- 8x Digital I/O lines
- 1x External Voltage Inset Connector
- 1x Physical Interlock
- 2x 10Gigabit Ethernet with PoE++ and IEEE1588 support
- 8x Laser Power Indicator LEDS

Slave Module - This module features:
- 10x Optical inputs (Laser + Photodiode)
- 1x External Voltage Inset Connector
- 1x Physical Interlock
- 2x 10Gigabit Ethernet with PoE++ and IEEE1588 support
- 10x Laser Power Indicator LEDS

These two modules can operate independently or daisy-chained with a maximum of 3 modules (Master + 2 Slaves usually) from a single PoE++ source. However, for situations where external PoE++ power is not available and / or external IEEE1588 is not available HGL has also designed a Base module which provides ancillary services.

Base Module - This module features
- DC Power (12-36V)
- 1x external 10Gigabit Ethernet Port
- 1x GPS antenna port (Option for 1x IRIG A/B port)
- 3x Lightning10-BTT Ethernet Ports with PoE++ and IEEE1588 support
- Optional internal solid state storage (up to 512GBytes)

The Lightning10-BTT modules are presented in a compact Milled Aluminium Hard Anodised Chassis (241mm x 89mm x 89mm) and is ideal for harsh Environmental locations including on / near Vehicle applications.
