Card with 4 controlled Output channels of 2.5A for the command of solenoids with safety related functions. It performs testing every 2 seconds on the channels cyclically, in case of discrepancy between the set signal and the read signal, the unit promptly warns about the failure condition. The Output is tested for the following: line opening, short circuit towards positive pole, short circuit towards negative pole, failure of piloting DMOS device, over-temperature of piloting DMOS device, power voltage outside the limits allowed. To increase output current, channels can be connected in parallel.
