J25 Hydraulic Power Unit Connections for the Model 494.44 System I/O Board
Connector J25 HPU provides 24-volt logic signals that control the hydraulic
power unit (HPU). The connector may be connected directly to MTS Series 505
HPUs and similar HPUs that use low-current, 24-volt input controls.
Note Other MTS HPUs require the Model 493.07 HPU Converter Box to
convert the low-current HPU output signal to a signal that can drive the
HPU relay.
