Original New MTL2000 range MTL2210B Switch operated relay ~ 1-channel was Discontinued now
The MTL2210B enables two 500VA safe-area loads to be controlled in separate circuits simultaneously by one light-duty on/off switch in a hazardous area. Alternatively, it can be arranged to latch for pushbutton stop/start control of an electric motor, the relay then being energised by brief closure of one switch contact and de-energised by the brief opening of another. The stop switch overrides the start switch, even if the start circuit is closed, making sure that the motor can be turned off under all conditions. In this application, the second pair of changeover output contacts enables the status of the motor to be fed to a computer or data logger.
