– The following variants are available, depending the operating
concept
– RolloTec cutoff relay [2930] and RolloTec cutoff relay RMD [2931] for
simultaneous movement two motors using one control section
– RolloTec cutoff relay [2969] and RolloTec cutoff relay RMD [2919] with
extension circuits for simultaneous movement two motors using
one control section separate operation the individual motors.
