Description
The AOS124 is a four-channel analogue current-output switch used in redundant ALSPA P320 TGC and P320 AVR architectures. For each channel it selects the active controller path, provides feedback for signal readback, maintains a current path for the non-selected channel and preserves loop continuity if the readback circuit is disconnected.
Depending on the system variant, the module interfaces redundant TGC outputs (usually to Vickers card) or links P320 AVR analogue outputs to the PAMOS4 acquisition module.
Please check compatibility with the installed hardware and system configuration before ordering.
