The ALO42S G2 Module provides 4 output channels for generating analog signals. By providing its own Module status to the Device Under Control (DUC), the status of the ALO42S G2 Module can be detected and fault conditions handled safely. The ALO42S G2 Module can also monitor the DUC by monitoring the test chamber control signals or relays. Should the DUC enter a fault condition, the PAK MKII has various options to safely handle the fault condition.
