- Monitors a wide variety of safety and non-safety input devices:
- Optical-based safeguarding devices, such as Safety Laser Scanners
- Positive-opening safety switches used for guard interlocking
- Emergency-stop devices, such as palm buttons and rope/cable pulls
- Standard sensors for non-safety applications, such as photoelectric monitoring position or end-of-travel
- The safety inputs can monitor:
- +24V dc solid-state (PNP) outputs in single-channel or dual-channel hookup
- +24V dc source that is switched by hard/relay contacts in single-channel or dual-channel hookup
- Hard/relay contacts in a dual-channel hookup using terminals S11-S12 and S21-S22
- UM-FA-9A: Three normally open (N.O.) output switching channels for connection to control-reliable power interrupt circuits
- UM-FA-11A: Two normally open (N.O.) and one normally closed
(N.C.) output switching channels for connection to control-reliable
power interrupt circuits
- Automatic reset or monitored manual reset, depending on hookup
- Design complies with Category 4 PLe (ISO 13849-1), SIL 3 (IEC 61508/IEC 62061), and Control Reliable (ANSI B11.19)
- Safety Integrity Level (SIL) 3 (IEC 61508/62061)
- Performance level (PL) e (ISO 13849-1)
- For use in functional stop category 0 applications per ANSI NFPA 79 and IEC/EN 60204-1
