Specifications

JX/256 Multiplexer with Keypad Manual Control and Display
JX-1
Size - Standard 19" rack mounting chassis, 5.25" high and
16" deep.
Prewired Backplane accepts 16 Switch Modules and one
Control Module. The Backplane includes signal bussing
so that the Switch Modules can be interconnected up to a
512x1 Multiplexer or 256x2 Matrix.
JX/256 Mainframe - This is a stand alone unit with its
own Power Supplies controlled from any one of the Control
Modules. It can also be supplied with an optional Manual
Control and Front Panel LCD Display.
Optional Dual Supplies - Standard power supplies allow
up to 150 relays to be closed simultaneously. Dual sup-
plies can be provided for applications requiring over 150
relays being closed at one time.
JX/256-E Expansion Chassis - These chassis obtain
their power and control from the MESA Series Control Units
as detailed in the MESA Bulletin and any number of
Expansion Chassis can be interconnected to make up large
multiplexers.
JX/256-E-PS Expansion Chassis w/Power Supply -
These Expansion Chassis can be provided with Power
Supplies for applications which require closing over 150
relays within the same chassis simultaneously. Call and
discuss your application to determine if you need this
option.
-W Option - The Mainframes or Expansion Chassis can
be supplied with all signals wired out to special, user
specified connectors on the rear panel. Consult Factory
for pricing.

or dual multiplexer.
Matrix Mode - Any number of Switches can be selected
at the same time.
Manual Controls - Switches can be selected by op-
tional front panel keypad with LCD display.
Status - Status feedback to the controller verifies the
position of the relays.

This compact and economically priced Series can be used as either Multiplexers, Matrices
or Individual Switches. As Multiplexers, they can be used as a single multiplexer to switch a
large number of inputs or outputs to one commpon port , or as a dual multiplexer to switch
between either of two common ports. As Matrices, any number of switches can be selected
and wired out in the required configuration. Individual Relays are available as SPST or SPDT
with standard, mercury wetted or power relays.
