presents a new range of electrical control boxes suitable for monitoring safety switches used with safety guarding on industrial machinery.
The Australian Standard, AS4024.1-2006, Safety of machinery outlines a level of risk procedure that leads to a determination of the Category of the interlocking circuits to be used when wiring up safety guarding interlocking switches. On some machines such as medium and large sized lathes, it is likely that the determined Category will be Category 4, which calls for dual monitored circuits.
CPR’s new electrical control box featuring power supply, dual 11Kw rated contactors and a twin channel monitoring relay helps make monitoring a relatively simple task for on-site electricians.
CPR Safe - Ind also offers electrical control boxes to handle heavier switching currents on request. While this control box is generally sold along with machinery safety guards such as for lathe chucks, the SafeInd Category 4 control box is available as a standalone product.
