General Specifications - Renishaw TONiC T20 1 Series Installation Manual

General specifications

Power supply 5 V ±10% T20x1 <100 mA
T20x1 with Ti0000 <100 mA
T20x1 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 120 Ω.
For analogue outputs, a further 20 mA will be drawn
when terminated with 120 Ω.
Power from a 5 V dc supply complying with the
requirements for SELV of standard EN (IEC) 60950.

Angular speed depends on ring diameter - use the following equation to convert to rev/min.
V x 1000 x 60
Where V = maximum linear speed (m/s) and D = external diameter of REXM/REXT (mm)
Angular speed (rev/min) =
π
D
NOTE: TD maximum speeds are resolution dependant as defined above.
