1 / 12 page 2-34 Presence Sensing Safety Devices Safety Light Curtains Perimeter Access Control Description Multi-beam safety light curtains from Rockwell Automation are infrared protection devices with 1 to 4 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 pr EN 50100 requirements, safety category 4, in that it is a self monitoring device. • Integrated evaluation with state-of-the-art electronics and especially 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 2) • Optical synchronization of sender and receiver units • Multiple safeguarding by means of corner mirrors and columns • Operating modes: • Electronic Device Monitoring (EDM) • Restart Interlock • Muting configuration available The devices were designed for industrial applications and offer the following advantages: • Beam coding for optimal interference immunity • Adaptability for safe PLC • Robust modular construction • Universal application possibilities • Simple installation Specifications Maximum scanning range 70m Maximum beam gap 500mm Minimum beam count 1 beam Maximum beam count 4 beams Minimum housing length 320mm Maximum housing length 1800mm Standards EN 50100 Approvals BG and CE marked for all applicable directives Protected Height Depends on product selection Scanning Range 70m (225ft), single beam PAC 7.5m Beam Gap Depends on product selection Enclosure Rating IP 65 Connection Type 7-pin mini style on transmitter and 8-pin on receiver Supply Voltage Uv Maximum Residual Ripple 24V DC ± 20% 5 Vss Power Consumption 7 watts—Transmitter 6 watts—Receiver Synchronization Optical, without separate synchronization channel Outputs Minimum output voltage 2 x PNP, 0.5 A, short circuit protected Uv - 2V Response Time ≤20ms Protection Short circuit and overload Connection Max. wire cross section 1.0mm2 with jacket 1.5mm2 without jacket Cable length 60m (196.8ft) maximum Protection against over-voltage ( ≥1kV) from Level 3 or higher (IEC 801 part 5; 2 kV) between PE and +V. Mode of Operation Guard-only with manual restart Safety Category Type 4 (self-checking) Requirement According to EN 50100 Operating Ambient Temp. 0°C to 55°C (32°F to 131°F) Air Humidity 15%...95% (not condensing) Storage Temperature -25°C to 70°C (-13°F to 158°F) Approximate Dimensions Height Housing Cross Section Length dependent upon protected height; (see dimensional drawings) 52 mm x 55 mm (2.05in x 2.17in) |
