•
A Series 256 Servovalve can be controlled with a Model 493.15
3 Stage Valve Driver mezzanine card.
•
A Series 257 Servovalve can be controlled with a Model 493.15

Improper operation can damage valve driver cards.
Damage can occur if you connect a high-level signal to a valve driver card
when the chassis power is off.

off. Disconnect power from any externally powered devices before you switch the
chassis power off.
