speed indicator / frequency / with LED display / totalizer
with LED display
RS-232, totalizer, HTL, RS-422, TTL
Universally applicable frequency and speed display with two incremental inputs for simultaneous acquisition of two independent speeds or speeds via encoders, proximity switches, photoelectric sensors, etc.
• Adjustable operating modes for speed, baking time (reciprocal speed), sum or
Difference measurement, ratio or percentage deviation etc.
• Different versions available: (Same as SA series, but without analogue output)
