BEFORE INSTALLATION
IMPORTANT
It is recommended that the controller be kept at room
temperature for at least 24 hours before applying
power; this is to allow the evaporation of any
condensation resulting from low shipping / storage
temperatures.
US requirement, only: This device must be installed
in a UL-listed enclosure offering adequate space to
maintain the segregation of line voltage field wiring
and Class 2 field wiring.
CAUTION
To avoid electrical shock or equipment damage, you
must switch OFF the power supply before attaching /
removing connections to/from any terminals.
MOUNTING
Both models have the same dimensions (W x L x H =
110 x 180 x 60 mm) (see Fig. 2) and conform to IP20 (without
optional terminal protection cover) or IP30 (with optional
terminal protection cover; width is then 130 mm).

Terminal Assignment
The Excel Smart I/O Compact features two rows of terminal
blocks located on one side for the connection of cables to the
inputs and relay outputs as well as for connecting the removable power supply terminal plug and removable
L
ONWORKS terminal plug.
NOTE: All relay and power supply terminal blocks are
orange-colored.
NOTE: According to VDE guidelines, it is not allowed to mix
low-voltage and high-voltage signals on the relays.
The Excel Smart I/O Compact is equipped with an adhesive
terminal assignment label on the top of the housing (see Fig.

Power Supply
General Information
NOTE: All wiring must comply with applicable electrical
codes and ordinances. Refer to job or manufacturers’ drawings for details. Local wiring guidelines (e.g. VDE 0100) may take precedence over
recommendations provided in these installation
instructions.
NOTE: To comply with CE requirements, devices having a
voltage of 50...1000 Vac or 75...1500 Vdc but
lacking a supply cord, plug, or other means for
disconnecting from the power supply must have the
means of disconnection incorporated in the fixed
wiring. This means of disconnection must have a
contact separation of at least 3 mm at all poles.
Use a minimum of 18 AWG (1.0 mm
14 AWG (2.5 mm
2
) for all power wiring.
Power is supplied via a removable terminal plug (attached to
terminals 25 and 26) permitting individual Excel Smart I/O
Compacts to be disconnected from the power supply without
disturbing the operation of other devices powered by the
same source. See Fig. 5.

may result in short circuits damaging your device.

LonWorks Communications
General Information
The Excel Smart I/O Compact is equipped with a freetopology transceiver for communication on L
networks. The L
ONWORKS network is insensitive to polarity,
eliminating the possibility of installation errors due to
miswiring.
Different network configurations (daisy-chain, loop, and star
configurations, or any combination thereof) are possible (see
also Excel 50/500 L
ONWORKS Mechanisms Interface
Description, EN0B-0270GE51).
Connecting to the LONWORKS Network
IMPORTANT
Do not bundle wires carrying field device signals or
LONWORKS communications together with highvoltage power supply or relay cables. Specifically,
maintain a min. separation of 3 inches (76 mm)
between such cables. Local wiring codes may take
precedence over this recommendation.
IMPORTANT
Try to avoid installing in areas of high electromagnetic noise (EMI).
The unit must be wired to the L
IV 22 AWG (Belden part number 9D220150) or plenum-rated
level IV 22 AWG (Belden part number 9H2201504) nonshielded, twisted-pair, solid-conductor wire. When possible,
use Honeywell 111AK3781, AK3782, AK3791, or AK3792
cable (US part numbers). See Excel 50/5000 L
Mechanisms, EN0B-0270GE51, for details, including
maximum lengths.
Use wire with a minimum size of 20 AWG (0.5 mm
maximum size of 14 AWG (2.5 mm

EXCEL SMART I/O COMPACT
Depending upon the chosen network configuration, one or two
terminations (see section "L
ONWORKS Termination" on page
6) may be required.
Inputs/Outputs
Wiring the Inputs/Outputs
Use a minimum size of 20 AWG (0.5 mm2) and a maximum of
14 AWG (2.5 mm
maximum length of all input/output cables is 400 m.
Two wires with a total thickness of 14 AWG can be twisted
together and connected using a wire nut (include a pigtail with
this wire group and attach the pigtail to the individual terminal
block). Deviations from this rule can result in improper
electrical contact. Local wiring codes may take precedence
over this recommendation.

Configuring the Inputs and Outputs
You can configure the Excel Smart I/O Compact’s inputs and
outputs using Honeywell's LNS plug-in or CARE.
NOTE: The switching logic functionality can be configured
using CARE, only. The LNS plug-in does not support
the switching logic functionality.
Digital Inputs
The Excel Smart I/O Compact is equipped with three digital
inputs suitable for use as fast digital inputs (static digital
inputs or push-buttons for flip-flop) or as totalizer inputs
(square waves).

inputs as
closed < 400 Ω < 0.8 Vdc max. 2.5 mA

For all NTC20k sensor inputs, temperatures of ≤ -50 °C are
interpreted as being due to a sensor break, and temperatures
of ≥ +150 °C are interpreted as being due to a sensor shortcircuit.
Relay Outputs
The Excel Smart I/O Compact is equipped with three
normally-open relay outputs.
Current Limitations
NOTE: If inductive components are to be connected to the
relays and if these relays switch more often than
once every two minutes, these components must be
prevented from causing harmful interference to radio
or television reception (conformance with
EN 45014).
• A min. current of 50 mA is required to ensure a reliable
contact.
• The normally-open contacts are designed for a max. continuous current of 3 A at max. 230 Vac and cos φ = 1. The
d.c. characteristic is shown in Fig. 8.

Replacing the Fuse
NOTE: Before replacing the fuse (see also Fig. 1 on page
1), disconnect the Excel Smart I/O Compact from the
power source by detaching the removable terminal
plug attached to terminals 25 and 26.
CAUTION
Depending upon actual wiring, even after you have
switched OFF the power supply, the relays may still be
under high voltage.
Troubleshooting
The Excel Smart I/O Compact features a LONWORKS service
LED and corresponding L
