Relay and Electronic Box

Electronic Box

The electronics module amplifies, filters and monitors the voltage signal sent from the sensor. When iron is detected, the module reads the voltage signal and activates the feed roll stopping mechanism.

The module is capable of filtering interference signals such as radio, television, CB radio and gas engine ignition systems signals.

The metal detector system has on-board diagnostics which will allow the operator to check the system for proper operation.

The electronics module cannot be repaired and must be replaced when diagnosed as a failed part.
