Abstract

PURPOSE:To operate the state of a load to the safety side forcedly, by driving forcedly the on-side relay coil when the operation signal processing circuit of the slave machine becomes faulty in the remote load control device. CONSTITUTION:When signal processing circuit T which processes the operation signal sent from the master machine to the slave machine and controls load Z becomes faulty, a control signal to make forcedly Zener diode ZD conductive is sent from the master machine to make Zener diode ZD conductive forcedly, and on-side relay coil R is driven to close the relay contact, and load Z is operated forcedly to the on-state, namely, the safety state. Conseuquently, the state of load Z can be forcedly set to the safety side, and the trouble where the load is not turned on unless the fault of signal processing circuit T is repaired completely can be prevented.
