Model 3510 is Tricon’s TMR Pulse Input card designed for 20 Hz – 20 kHz signals from passive magnetic pickups on compressors, turbines, pumps or flow-meters.
Eight non-commoned, fully-differential channels deliver 1 µs resolution and 0.01 % accuracy at 1 kHz+, while triple-channel voting keeps SIL-3 integrity intact.
Typical uses include speed control, overspeed-trip verification, anti-surge logic and flow-rate calculation in oil & gas, chemical and power plants.
