5 V ±10% Readhead only < 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 120R.
For analogue outputs a further 20 mA in total will be drawn when terminated with 120R.
Power from a 5 Vdc supply complying with the requirements for SELV of standard IEC 60950-1.
