With the growing demand for simple, efficient and more secure safety systems, the ISIS system offers the ideal solution.

Available in a range of voltages, the ISIS control units provide two normally-open safety contacts and one normally-closed auxiliary contact.

A major advantage of the ISIS safety system is that it detects both open and short circuit faults in the connections to the switch when they occur, giving immediate indication and moving the control unit to a safe state.  This eliminates the possibility of faults accumulating without being detected.

The ISIS-4 control unit can also be used to monitor the emergency stop buttons or mechanical safety switches, combining both safety functions into one DIN rail mountable unit.

The ISIS-E Extender modules can be added to either the ISIS-4 or ISIS-2 control units giving ISIS switch inputs for monitoring larger systems.

ISIS switches can only be run by ISIS controllers. ISIS safety switches use coded magnet technology, are compact, tamper-resistant and yet still have 8mm switching and IP 67 environmental protection.  This makes them ideal for all types of applications where additional security is required.

Connect the required number of safety switches to the ISIS control unit (an internal switch is used to select how many are in operation).  With the power on and all the safety switches closed the system self check is performed.

The output safety contacts will only close if all activated safety contacts are operating correctly and the internal self checking is completed successfully.
