Motion Monitor for Secure and Redundant Control of 2 Drive Systems MS640

•The Motrona range of position monitors are used to determine actual values such as speed, direction of rotation and standstill and compare them with preset reference values. •In the case of unwanted movement, the devices trigger a programmed fault message. •These safety relays are suitable for monitoring and avoiding misalignment, shaft breakage, torsion and slippage. •The high frequency range, fast response and ease of adjustability of the speed, direction and standstill parameters are the key features of the Motrona position monitors. •2 Pulse inputs with format A, B, 90° [HTL] or A, /A, B, /B [RS422] •4 control inputs for PNP / NPN / Namur signals [10 ... 30 VDC] •6 logical inputs for PNP signals [10 ... 30 VDC] •Input frequency up to 500 kHz •4 fast transistor outputs with push-pull characteristic, short-circuit-proof [5 ... 30 VDC] •4 forced-guided redundant output relays with potential free change-over contact
