Dold Motor Brake Relay The BA9034N incorporates automatic standstill monitoring alongside a contactor connected to the DC relay output. Motor restart while DC braking current injection can be avoided thanks to an inter-lock contact & built in safety brake.Asynchronous motor brake relays are suitable for a variety of both single & three phase motors. A potentiometer allows for adjustment of the braking current scaled from 10-100%, accompanied by an integrated current limit which scales to the current % settingFeaturesSuitable for both single & three phase asynchronous motorsAutomatic standstill detectionIntegrated braking contactorEasily fitted into existing installations as well as new applicationsMicrocontroller enabledBenefits of the BA9034NCost effectiveNo need to monitor currentCompact designHigh level of safety & more economic thanks to short stop cyclesDC Brake Modules A powerbrake unit is used where fast, efficient and predictable stopping of a machine in the shortest possible time is required. Using the d.c. injection method, it provides a controlled deceleration to a stop, by injecting a d.c. current into two of the motor terminals and neutralising the rotating magnetic field in the motor after the 3 phase supply has been disconnected. This stops the motor coasting to a halt and reduces the delay time by this enforced braking. They can be used with a standard 3 phase induction motor. The unit may be located on a piece of machinery or adjacent to it, with little disruption or modification required to the existing wiring. The Powerbrake units provide a simple cost-effective solution to motor braking, which is maintenance and wear-free.,Brake Module - For a brake unit, all the control wiring has to be supplied and installed by the customer, including interlocked contactors and pushbuttons.,Production Brakes - Enclosed brakes with all control wiring included, optio...
