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: BO1, BO2, BO3, BO4,
(Relay outputs), BI1, BI2, BI3, BI4 (Dry
contact inputs)
• Device Instance changed via Object
Identier Property of Device Object
• Each unit is 1/8 unit load
• PIC Statement available on website.

• Dry contact digital input is a general purpose input that
is not tied to the relay internally. Can be used with any dry
contact switching device, such as a current sensor, to report
back to the network.
