ICS-9 Interlock® Controller – NRTLThe ICS-9 NRTL Certified Laser Interlock® Control System

The ICS-9 Laser Interlock® Controller is the successor to the highly successful ICS-6 (which it directly replaces).

  • This compact unit can control laser interlocks, magnetic door locks, LED warning signs and can operate laser shutters. It enables the laser to be powered by controlling the laser safety input. It has feedback monitoring and fault detection. It can be interfaced to Access Control and Fire Detection Systems and it is fitted with an Override to allow controlled access through interlocked doors while also accepting emergency stop inputs. The override is operated either by a push-button (on the inside of a laser controlled area), or by a keypad-operated override. (e.g. KP-14)
  • The ICS-9 has full start-to-end dual channel architecture and fault detection to meet the latest safety standards to a much higher level than single channel systems.
  • It has a simple, easy-to-use control panel and can be connected directly to nine interlocks (or groups of interlocks).
    The standard ICS-9 has 9 volt-free interlock operator output contacts which may be used for various purposes including:

    • Switching laser power
    • Controlling beam shutters
    • Operating the laser’s interlock input
    • Controlling door locks
  • It is compatible with the ICS Buddy – the portable laser interlock controller. The ICS Buddy can mirror the function of the ICS-9 remotely
  • It has NRTL Certification and therefore approved for use throughout the USA.
    OSHA’s Nationally Recognized Testing Laboratory (NRTL) Program recognizes private sector organizations so they can perform certification for certain products to ensure that they meet the requirements of both the construction and general industry OSHA electrical standards.
    The interlock has been tested by TÜV SÜD America Inc. to IEC 61010-1 Safety requirements for electrical equipment for measurement, control, and laboratory use. Part 1 General requirements.
    The product fulfils the requirements of CAN/CSA C22.2 No. 61010-1:2012, UL 61010-1:2012 and EN 61010-1:2010


Flexible Expandable System

It is designed to achieve EN ISO 13849-1 PLe (to achieve performance level ‘e’)

The standard ICS-9  has a deep back box so that contactors can also be added to give interlocked 32A single phase and 3 phase mains supplies. The ICS-9 can be connected to other Lasermet Interlock® controllers to operate as a primary or secondary unit.

ICS-9 has an expansion socket and can be fitted with up to 3 expansion cards (which are automatically tested). There are 4 different types of card as follows that can be fitted:-

Key Details
  • Expansion card sockets to enable the following:-
  • Compatible with ICS-Buddy – the portable laser interlock controller.
  • Integrated Active Laser Guarding (Laser Jailer)
  • Safety Logic Plus integration, (for complex logic circuits and large numbers of Interlock® switches)
  • Ethernet/USB Connectivity which in turn enables ICS-9 interlocks to be monitored remotely – a real bonus to safety communications
  • Full start-to-end dual channel architecture – for even higher reliability
  • Full start-to-end fault detection – simplifying analysis
  • Interlocked mains supply – for added safety
  • Interlocked low voltage supply for beam shutters – for faster integration
  • Laser Interlock® connector operators – for all lasers
  • Key-switch operation – to prevent unauthorised use
  • Arm laser button – just press to arm
  • Time limited fail-safe override option – for authorised personnel
  • Automatic switching of illuminated signs – indicating danger or safe modes
  • Emergency stop circuit – to prevent injury or damage in an emergency

ICS-9 can be configured as a locking or non-locking Interlock® system featuring:

  • Automatic fault detection and shutdown
  • LED indication for the Status of the following:
    • Interlock® Switch
    • Expansion
    • Emergency Stop
    • Safety Circuits OK
    • System Overridden
    • Safety Circuit Fault (Mismatch Fault)
    • Laser Armed
  • Dual-redundant fail-safe circuitry
  • Dual Channel Override control
  • Feedback-based Sign Control – to maintain warning sign at Danger if the Shutter/power control fails to go to the safe condition when the system is disarmed

Further functions:

  • Can be used as a local laser controller as part of a larger system, which may be controlled by a master Interlock® controller
  • Optional safety status and ready status outputs can be provided to communicate with other Lasermet Interlock® controllers or a remote indicator panel
  • Surface-mounted, the ICS-9 has a “deep box” for expansion cards or safety contactors to switch high power or multiple lasers.
  • External facility to allow the system to be disabled by an external source e.g. supervisor’s key-switch
  • Operation of mains or low voltage signs
  • Integrated automatic switching of single or dual mode signs
  • Connect to virtually unlimited number of door contacts and Emergency Stop Buttons
