ogy, for driving inductive or resistive loads. An in-
ternal Clamping Diode enables the fast demag-
netization of inductive loads.
Diagnostic for CPU feedback and extensive use
of electrical protections make this device inher-
ently indistructible and suitable for general pur-
pose industrial applications.
