Features
SD 340-644: Speed Ratio Meter (RS232 interface)
SA 340-644: Speed Ratio Meter (RS232 interface, analog output)
SR 340-644: Speed Ratio Meter (RS232 and RS485 interface)
- Measuring functions: tachometer, ratemeter, and frequency counter with two independent encoder inputs for use with incremental encoders, proximity switches, photocells
- Both impulse inputs with individual scaling, each adjustable to 1, 2 or 4 tracks (A, /A, B, /B), suitable for frequencies from 0,01 Hz up to 1 MHz
- Programmable operating modes for rpm, speed, processing time (reciprocal speed), sum speed or differential speed, speed ratio and percentaged speed difference
- 4 preselections with fast-switching outputs and programmable
maintain / latch / start-up delay functions - Adjustable filtering functions, programmable linearization and more
- Power supply 24 VDC or 24 VAC, dimensions 96 x 48 mm (3.780" x 1.890")
