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.
