Characteristics of the digital outputs
● The digital output states are always indicated by the LEDs DO0-DO15 on DA501 module.
● All 16 outputs have the same potential ZP as all other inputs/outputs. The electrical isolation
included in the existing devices is no longer available.
● Diagnosis: Stored errors are indicated via an LED and can be accessed by the CPU (see
AC500 documentation).
