J28 HSM Connections for the Model 494.42 System Board
HSM control (off/low/high or proportional) is software configurable. The Model
494.42 board provides separate 24-volt, low-pressure and high-pressure outputs
that drive the HSM low- and high-pressure solenoids. Proportional solenoid
control provides a current output from 0 to 0.78 A.
Note The Model 494.42 board can not be used with 115 V AC HSMs.
Applications that use 115 V AC HSMs require an external converter box
(such as a Model 413.08), which is used with this board.
Cable specification
To maintain EMC compliance, J28 HSM cables must comply with the following
specifications:
Connector—9-pin type D male EMI connector.
Backshell—EMI metallized plastic or metal.
Proportional Control Cable—18 AWG, 2-conductor with foil shield drain wire
connected to conductive backshell.
Off/low/high Control Cable—18 AWG, 3-conductor with foil shield drain wire
connected to conductive backshell.
