UM-FA-9A

UM-FA-9A is a safety relay module for safety light curtain/scanner/E-Stop/interlock. It features three normally open (NO) output switching channels for connection to control reliable power interrupt circuits. It 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: +24VDC solid-state (PNP) outputs in single-channel or dual-channel hook-up, +24VDC source that is switched by hard/relay contacts in single-channel or dual channel hook-up, Hard/relay contacts in a dual-channel hook-up using terminals S11-S12 and S21-S22.

• Automatic reset or monitored manual reset, depending on hook-up
