The TB20 quadrature trigger box can be used to remotely trigger the XL-80 laser. It monitors the position feedback signals between a machine's encoders and its controller, and feeds trigger signals to the XL-80. This allows synchronisation of scale position or movement to the XL-80 data capture. TB20 is primarily used in applications such as leadscrew or encoder system calibration.
The TB20 is mains-powered and works with TTL quadrature or analogue current loop encoders and triggers the laser measurement at regular user-defined intervals.
