TAIT’s NAV:ESA is a network-based, master emergency stop controller that is capable of supporting 90 devices and is compliant with the highest safety standards. It is FSOE compliant which reduces the requirement for a separate Estop connection for external devices. Bypass is available for all channels with utilization possible only after internal safety checks are complete.
The ESA is also EN 61508 SIL 3 and ISO 13849 PLe compliant with continuous hardware and software validation. Connections are made through the same Ethernet switches and cables as used in Navigator network. The controller can interface with legacy ESE controllers using an optional expansion card.
