The Elfatek RIO-AC1 is an external digital display and load control indicator in one unit. It measures the signal from a load cell with high precision, shows it on a 6-digit LED display and gives a warning when the lifted load exceeds the crane capacity, so the lift does not continue – helping to prevent accidents and material damage.
All parameters are set with the remote control, so nobody has to climb to the device; they can also be changed via CANOpen. Through the CAN line it can set the parameters of an Elfatek rope angle limit sensor connected to the same line, and it can work with other control units over CANBus.
- 1 load cell input, 3 NO 10 A relays with adjustable positions
- 6-digit 7-segment LED display, 100 mm red digits, readable from 50 m indoors
- RS232 and CANBus communication
