EOT CRANE OVERLOAD PROTECTION ELECTRONICS WITH 1 OR 3 SET-POINTS

Reference :

Electronics with 1 or 3 set-points designed, in combination with a load cell, to limit the load and/or to detect slack cable on a hoisting device (EOT cranes).

o Low cost
o 1 or 3 independent set-points
o Set-points 1 and 2 configurated for load limitation
o Set-point 3 configurated by default for slack cable detection
o Adjustments by potentiometers
o Analogue outputs: 0...10 V and 4...20 mA
o Din rail mounting (TS 35)
o 115 VAC available by internal jumper
