The TR-EM-239 parallel controller, available from LINAK Australia , is designed to drive two actuators in parallel.
It is suitable for 12V to 24V DC motors with a maximum of 2 x 10Amp capacity and applications, where parallel movement is required, for example, across a bench, hatch, door, slide, transfer, directional guide, over a wide span and conveyor line.
The TR-EM-239 parallel controller works with actuators that provide pulse feedback signals. Pulses can be derived from hall-sensors, reed or switches that can accept either negative or positive pulses.
The actuators are synchronised using the pulse width modulation (PWM) to adjust individual actuator speeds.
For example, if one side of a bench is fully loaded and the opposite side has minimal load resulting in less load on the actuator, this actuator speed will be slowed to maintain the same PWM count as the actuator under load, thus maintaining synchronisation of both actuators.
If the controller cannot maintain parallel drive between the actuators, the actuators will be stopped, reducing the possibility of mechanical stress and breakage. The controller includes built in safe guards for current cut-off and power stage temperature limit protection.
Another feature of the TR-EM-239 parallel controller is the ability to operate in pulse or continuous operation modes. The basic control is done with forward, backward and stop commands.
Forward and backward input commands can be accepted in continuous or impulse signal modes. In continuous mode, the actuators will operate as long as the command signal is activated. In impulse mode, only an impulse signal is required to start and stop the actuator movement.
This solution provides an alternative system to pneumatics and hydraulics, which are generally costly and difficult to maintain true synchronisation.
The TR-EM-239 parallel controller is easily adjusted or can be provided preset from the factory to suit intended applications. Repeat orders can be duplicated prior to dispatch from LINAK Australia ready to use.
Controller operating parameters are adjusted such as actuator drive speeds, soft start and stop functions, pulse or continuous operation, current overload settings and sensitivity. These adjustments are carried out through portable serial interface handset (TR-EM-236).
The users need to plug in, adjust and operate. For advanced use, the TR-EM-236 parallel controller can provide controller information regarding current levels and pulse counts in monitor mode.
The TR-EM-239 parallel controller is available in PCB for DIN rail mounting or enclosed in an IP66 enclosure. These controllers can be installed in LINAK Australia’s power supplies.
