About the Model 493.74 Two-Station HSM Interface Board
The Model 493.74 Two-Station HSM Interface
board is a double-width board that plugs into the
transition card cage on a Series 494 Chassis.
Each Model 493.74 HSM transition board
controls up to two stations.
Each station has the following connections:
• 24-volt hydraulic service manifold (HSM)
control (off/low/high or proportional) (J28
HSM)
• E-Stop and crosshead controls for a load
unit control module (J29 Load Frame)
• Inputs that can initiate station and program
interlocks (J43 Interlock)
• Remote run/stop outputs for external
devices (J44 Run/Stop)
• Auxiliary power outputs for external
devices (J49 Aux Power)
