The Lasermet ICS-9 Laser Interlock® Controller is the successor to the highly successful ICS-6, directly replacing it. 

The compact ICS-9 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.

 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
  • Full start-to-end dual channel architecture and fault detection
  • Interlocked mains supply 
  • Interlocked low voltage supply for beam shutters 
  • Laser Interlock® connector operators for all lasers
  • Time limited fail-safe override option 
  • Automatic switching of illuminated signs indicating danger or safe modes
  • Emergency stop circuit to prevent injury or damage in an emergency


The ICS-9 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 ICS-9 has been tested by TÜV SÜD to IEC 61010-1 Safety requirements for electrical equipment for measurement, control, and laboratory use. Part 1 General requirements. It also fulfils the requirements of CAN/CSA C22.2 No. 61010-1:2012, UL 61010-1:2012 and EN 61010-1:2010.


The ICS-9 is compatible with the ICS-Buddy – the portable laser interlock controller. The ICS-Buddy can mirror the function of the ICS-9 remotely.


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:

  • Compatible with ICS Buddy – the portable interlock controller
  • Remote Communications (Ethernet/ USB Connectivity)
  • Integrated Active Laser Guarding
  • Safety Logic Plus integration


The standard ICS-9 has 9 interlock outputs rated 8A at 110/250VAC/50VDC. An optional contactor enhancement adds 4 interlock mains outputs rated 32A at 415VAC.

Max output current using internal power supply is 1A. An additional Power Supply provides enhanced current output.

An unlimited number of interlock switches can be connected to the ICS-9. Monitoring is available for 4 switches or groups of switches. Likewise, an unlimited number of Emergency Stops can be connected and integrated into a Fire Alarm or Access Control System.
