Document Type and Number:
WIPO Patent Application WO/2014/041883
Kind Code:
A1
Abstract:
A relay control unit (1a) is provided with a control circuit (2a) for calculating external information such as the temperature of a relay (6) detected via a temperature detection circuit (11), the on/off state of another adjacent relay, an oscillation value detected by an oscillation sensor (4), and a coil voltage monitored by a voltage monitoring circuit (5), and changing a control value for PWM control of the relay (6) on the basis of the calculated information.
