Perimeter Access Control (PAC)
|
Description
Multi-beam safety light curtains from Rockwell Automation are infrared protection devices with one to four infrared beams. They operate on the through-beam principle, consisting of a sender and receiver unit and are suitable for access control and perimeter guarding.
The PAC fulfils the EN 50100 requirements, safety category 4, in that it is a self-monitoring device.
- Integrated evaluation with state-of-the-art electronics and specially developed ICs (ASICs)
- Beam coding for high interference immunity
- Actively monitored semiconductor outputs
- Mini style quick disconnect connectors
- Fast response time
- Large signal reserve (factor two)
- Optical synchronization of sender and receiver units
- Operating modes:
- Electronic Device Monitoring (EDM)
- Restart Interlock
- Electronic Device Monitoring (EDM)
- Muting configuration available
The devices were designed for industrial applications and offer the following advantages:
- Beam coding for optimal interference immunity
- Robust modular construction
- Universal application possibilities
- Simple installation

Product Selection
1a. Multiple-Beam PAC
The Allen-Bradley Guardmaster PAC multiple beam safety light curtains are ordered as pairs—transmitter and receiver—and shipped under one part number. After selecting the appropriate light curtain pair, ensure that required interfaces and accessories are ordered as well. The single-beam PAC can be ordered with a passive mirror column (440L-AMIRSTDZ500) or two right angle mirrors (440L-AMIRR2).

Note: For the 440L PAC unit, set the DIP switches as follows:
SW 1, 5, 6, 7, 8 to “B”
SW 2, 3, 4 to “A”
The DIP switches are accessed by removing the connection cap of the receiver unit. The sender unit will not need DIP switch configuration if these receiver settings are used.
