ICT42S G2

The ICT42S G2 Module is a hybrid Module which combines 2 channels from the advanced ICP42S G2 Module with 2 advanced tacho input channels. The tacho channels provide tacho period measurements with a 14 ns resolution, sampled where the signal intersects its trigger level settings. Triggering of tacho signals can be set for rising or falling edges with adjustable hysteresis whilst additionally providing AC coupling for sensors with varying DC voltage offsets. A high speed 4.9 MSa/s scope mode is provided to view the tacho signals in order to assist with the definition of trigger levels.

• When measuring the pulse rate and time between pulses such as rpm and crank angle
• With any ICP^® based sensor commonly used to measure vibration, acceleration, force or pressure
• With any voltage source up to ±60 V in voltage input mode
