System Overview
Softswitch128
® is a switching system that is ideal for
small to medium sized switching projects. A system
consists of panels, control stations, occupancy
sensors, and photocells. Softswitch128
® panels contain
Lutron’s one million cycle Softswitch
® relay and the
Softswitch128
® Controller.
Softswitch128
® is easy to install and simple to
program. Softswitch128
® also includes a CEC/Title24
approved astronomical time clock for system automation.
System Features
• Digital control for up to 512 circuits.
• Add up to 32 digital control stations (wallstations and
interfaces) for multiple points of control.
• Up to sixteen (16) Softswitch128
® panels may be used.
• Add the Softswitch128
® Expansion Module
(XPS-E-120/277-FT) to the system for increased control
station capacity. Three links of up to 32 control stations
each (96 control stations total) may be added with the
Expansion Module present.
• Integrated CEC Title 24 listed astronomical time clock.
• Lutron
® Softswitch® technology for every switched
output (resistive, inductive and capacitve) to full 20 A
1
.
• Softswitch
® relays are rated for all light sources as well
as AC general use motors.
• RS232 interface available (OMX-RS232).
• Contact closure input and output devices available
(OMX-IO and OMX-CCO-8).
• Keyswitch wallstations available (NTOMX-KS).
• Normal or emergency panel capability.
• Softswitch128
® panel is prewired and pre-tested.
• Panels for 120/277 V~, 347 V~, and 480 V~
applications. Contact a Lutron
® representative for details
on 347 V~ and 480 V~ switching.
• 208 V~ loads are wired phase-to-phase in 120 V~
panels. See Lutron
® Application Note #102 for details.
• Feed-through, branch circuit breaker, and rough-in type
panels are available.

Overview
The Softswitch128
® Controller is used to configure
the entire Softswitch128
® system. The controller
features an LCD user interface to facilitate
programming all switching system and astronomical
time clock (ATC) parameters.
Features
• Program wallstations to recall light patterns, to toggle
any switch leg(s), to activate delay-to-off and to
activate contact closures on a button by button basis.
• Integrated astronomical time clock (ATC) automates
switching and contact closure outputs with up to
500user-defined events within 7 daily schedules and
40 holiday schedules. Each day may have 25 events.
• ATC events automatically select patterns, start
after-hours mode, or end after-hours mode.
• Events may be copied and pasted for fast
programming.
• ATC events may be triggered by time of day or by an
offset from sunrise or sunset.
• System location is programmable by internal city
database or by specifying latitude and longitude.
• ATC automatically adjusts for leap year and daylight
savings time (where applicable).
• Programmable after-hours mode with user-selectable
“blink warn” and user programmable refresh time.
• Two integrated user-configurable contact closure inputs.
• Override capability is available at the panel for
controls, timeclock, and switch legs.
• Controller is located in the Softswitch128
® panel for
easy access.

Load
•
When using the Switching Module to control
receptacles, it may be used with, but is not limited to,
the following:
– Monitors – Fans
– Humidifiers – Printers
Note: Refer to the manufacturer’s guidelines for
acceptable switching methods.
•
When using the Switching Module to control
receptacles, it may NOT be suitable for use with
devices that require any of the following:
– Shut-down process before power is interrupted,
such as computers.
– Cool-down process before power is interrupted,
such as projectors.
– Programming, such as clocks or DVRs.
– Long warm-up cycle.
•
Not for use with loads that present a hazard if
automatically energized, for example heaters.
•
Any receptacles that are controlled by an
automatic control device must be marked with “u”
located on the controlled receptacle outlet where
visible after installation as stated in 2014 NECR
Article 406.3(E).
Switching Modules (120, 277, 347 V~)
• Able to control 20 A receptacles.
• Switch legs rated at 20 A.
• Patented SoftswitchR circuit eliminates arcing at
mechanical contacts when loads are switched, which
prolongs relay life to an average of 1,000,000 cycles at
16 A.
• 10 BTU / hour per module.

Switched Load Wiring
Each switched circuit requires a dedicated 20 A circuit
breaker and feed wiring to/from a distribution panel.
Control Wiring
Control wiring requires a dedicated feed and circuit
breaker.
Wire Sizes
• 14 AWG to 10 AWG (2.5 mm
2
to 4.0 mm
2
) for Feed
Wiring and Switched Load Wiring.
• Power (Line / Hot) and Switched Line / Hot connect
directly to Terminal Block for Switch Legs.
Feed-through Softswitch128® Wiring Overview
Ground
Bus
Control Circuit
• Supplies power for internal operation.
• Lutron recommends a dedicated 120 V~ or
277V~, 20 A, 1 phase 2 wire feed to power the
control circuit in the panel.
• If control circuit is tapped from a circuit that powers
a relay in the panel, it draws a maximum of 1.5 A
toward the total load for that circuit.

Any receptacles that are controlled by an automatic control device must be marked with “u” located on the controlled receptacle outlet where visible after installation as stated
in 2014 NECR Article 406.3(E).
3
To avoid the risk of entrapment, serious injury, or death, these controls must not be used to control equipment which is not visible from every control location or which could create
hazardous situations such as entrapment if operated accidentally. Examples of such equipment which must not be operated by these controls include (but are not limited to)
motorized gates, industrial doors, space heaters, etc. It is the installer’s responsibility to ensure that the equipment being controlled is visible from every control location and that
only suitable equipment is connected to these controls. Failure to do so could result in serious injury or death.
Do not remove bypass jumpers until load wiring
is verified.
Leaving bypass jumpers installed allows
Softswitch128

temporary lighting, until load wiring is verified.

NOTES
• Emergency Power: The additional 18 AWG (0.75 mm()
wire is a “sense” line from terminal 5 of another Panel.
This sense line allows an Emergency (Essential) Lighting
Panel to “sense” when Normal (Non-Essential) power is
lost. If more than one Emergency Lighting Panel needs
to sense from a specific Normal Panel, a dedicated
wire between each pair of Normal (Non-Essential) and
Emergency (Essential) panels may be required.
• Shield/Drain: Connect shielding as shown. Do not
connect to Ground (Earth) or Circuit Selector. Connect
the bare drain wires and cut off the outside shield.
IEC PELV / NEC® Class 2 wiring link requires:
• Two 12 AWG (4.0 mm
2
) conductors for control wiring.
• One shielded, twisted pair 18 AWG (0.75 mm
2
) for data link.

(152 m).
Low-Voltage IEC PELV / NEC® Class 2 Wiring
• Low-voltage IEC PELV / NEC® Class 2 wiring is used for all system communications.
• Wiring must be daisy-chained.
• Low-voltage wiring must run in a separate trough from line (mains) voltage.
• Must be less than 2000 ft (600 m) long.
• Install Link Terminators (LT-1) at the start and end of the IEC PELV / NEC
