Renishaw encoder systems have been designed to the relevant EMC standards,
but must be correctly integrated to achieve EMC compliance. In particular,
attention to shielding arrangements is essential.
TONiC RGSZ installation guide
Readhead only <100 mA
T100x with Ti0000 <100 mA
T100x with Ti0004 – Ti20KD or TD4000 – TD0040 <200 mA
NOTE: Current consumption figures refer to
unterminated systems.
For digital outputs a further 25 mA per channel pair
(eg A+, A-) will be drawn when terminated with 120R.
For analogue outputs a further 20 mA in total will be
drawn when terminated with 120R.
Power from a 5 V dc supply complying with the
requirements for SELV of standard IEC BS EN 60950-1.
