[. . . ] 5. LonWorks Communications General Information The Excel Smart I/O Compact is equipped with a freetopology transceiver for communication on LONWORKS® networks. The LONWORKS 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 LONWORKS 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. 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 LONWORKS network using level 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 LONWORKS Mechanisms, EN0B-0270GE51, for details, including maximum lengths. Use wire with a minimum size of 20 AWG (0. 5 mm2) and a maximum size of 14 AWG (2. 5 mm2).

XFCL2A1 with 230 Vac Power Supply The XFCL2A1 with 230 Vac power supply is equipped with a built-in 24 Vac transformer. Power supply: 230 Vac [-15% / +10%], 50/60 Hz). Power consumption: < 6 VA (device unloaded) 3 EN1B-0282GE51 R0305B EXCEL SMART I/O COMPACT Depending upon the chosen network configuration, one or two terminations (see section "LONWORKS Termination" on page 6) may be required. Analog Inputs The Excel Smart I/O Compact is equipped with three analog inputs. The analog inputs may be used as NTC20k temperature sensor inputs or as slow digital inputs. The analog inputs do not support 0. . . 10 V input. Slow digital input characteristics Inputs/Outputs Wiring the Inputs/Outputs Use a minimum size of 20 AWG (0. 5 mm ) and a maximum of 14 AWG (2. 5 mm2) for all input/output connections. The 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. 2 software de- resistive input tects inputs as (dry contact) closed open < 200 > 50 k high/low switching at < 1. 5 Vdc > 3. 5 Vdc current out of terminal < 0. 3 mA < 0. 1 mA Table 4.
