Description

With the growing demand for simple, efficient and yet 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, 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 safety switches 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 mounting unit.

The ISIS-E Extender module can be added to either the ISIS-4 or ISIS-2 control units giving more ISIS switch inputs for monitoring larger systems. The ISIS safety switches use coded magnet technology, are compact, tamper-resistant, and yet still have 8mm switching and IP67 environmental protection. This makes them ideal for all types of applications where additional security is required.

Operation

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 switches are operating correctly and the internal self-check is completed successfully.

ISIS-4

The ISIS-4 control unit is available in 4 different input voltages and can monitor up to 4 ISIS safety switches.

The easy to install, 35mm DIN Rail mounting housing provides 2 x safety and 1 x auxiliary output contacts (4A / 230V ac). Indicator LED’s in the ISIS-4 lid show the number of gates that have been selected, gate status, power and run. A DIP switch located beneath the lid is used to select the number of active safety switches (note: The selector switch and number of safety switches must match or the control unit will not operate.)

ISIS-2

The ISIS-2 control unit can monitor up to 2 ISIS safety switches and is housed in a slim-line (22.5mm), DIN Rail mounting housing. This unit can accept either 24V ac or dc supply, and provides 2 x safety and 1 x auxiliary output contacts (4A / 230V ac). Indicator LED’s in the ISIS-2 lid show power, run and gate status. Like the ISIS-4, a DIP switch located beneath the lid selects the number of active safety switches (note: The selector switch and number of safety switches must match or the control unit will not operate.)

ISIS-E

The ISIS-E Extender module provides 5 safety switch inputs to an ISIS control unit ( ISIS-2 or ISIS-4) Multiple ISIS-E extender modules can be connected together into one system, making it possible to monitor large numbers of machine guards or to add gates to an existing system at a later date. The ISIS-E requires 24V ac/dc supply and a simple 2 wire connection from the ISIS-E to any active ISIS safety switch input. LED indication is available from all gate switches showing guard status.
