I am a newbie with absolutely no idea about electronics, so am in need of some help.
I have some 1um SINO KA Series Glass Linear scales.
I wish to splice into the signals, using optocouplers to feed into a second device.
I have Signals A, B, Z.
The Manual to the glass scale Says:
+5v(+-5%) 80ma
Maximum of 60cm per second
The DRO display console showing the scales position says:
Allowable Input signal: TTL square wave.
Allowable input signal frequency: >100K Hz
Power voltage: +5v
Signal: TTL Square signals are sent out from two channels with a phase difference of 90degree (with zero position signal) current 50mA
The device I am trying to optocouple to has internal resistors pulling logic High by default, +5v 100mA and max 500Khz input.
The scales would be powered by the DRO +5v
and the optos output side by the device +5v
I have directly wired the scales to the device and it works.
I need to know what opto to use, and it needs to be high speed to handle upto 100 or 500Khz.
Thanks
Carl
