Notes:
• Device can be powered by either 24 Vac/dc or
120 Vac, but not both.
• Order NEMA 4 housing by adding “-N4” to end
of model number. (RIBTWX2401B-BC-N4)
• Order with grey lid by adding “-GY” to end of
model number. (RIBTWX2401B-BC-GY)
• Order NEMA 4 housing with grey lid by adding
“-N4-GY” to end of model number.
(RIBTWX2401B-BC-N4-GY)
• When connecting 24 Vac to both the RIB(s) and a
half-wave device, damage to device can occur.
Option 1: Use separate transformers for each
device. Option 2: Add diode between devices,
see Option 2 note below. ^^
BACnet® Details:
• MS/TP Address & Baud Rate must be set prior to
power up via DIP switches.
Device ID will default to 277XXX where XXX is
•
the MS/TP Address.
Examples:
MS/TP Address - 004
Device ID - 277004
MS/TP Address - 121
Device ID - 277121
•
Device ID can be changed via network
command. Once changed, it will no longer
default to 277XXX. (MS/TP Address & Device ID
must be unique.)
• This model utilizes: BO 1 (Relay output),
BI 1 (Dry contact binary input), BI 2 (Internal
current sensor input)
• Device Instance changed via Object Identier
Property of Device Object
• PIC Statement available on website.
