24 V-NS DC
Electronics supply voltage
24 V-S DC
Switching element supply voltage
AS-Interface (AS-i)
The AS-Interface (or actuator/sensor interface; abbreviated to AS–i) is a connection system
for the lowest process level in automation systems.
BO
Brake output
Combined Transaction Type 2 (CTT2)
Communication protocol on AS-Interface in accordance with Specification V3.0 for the
transfer of large volumes of data (analog values, strings, etc.).
Degree of protection
The degree of protection of a device indicates the extent of protection. The extent of
protection includes the safety of persons against coming in contact with live or rotating parts,
and the protection of electric resources against the penetration of water, foreign bodies and
dust.
The M200D has an IP65 degree of protection when all the unused connections are sealed.
DSte
Abbreviation for "direct starter, electromechanical"
ESD
Components sensitive to electrostatic charge
Electronic components (e.g. field effect transistors, integrated circuits) that may be destroyed
by high voltages (for instance by electrically charged non-grounded persons)
