Analog Output Module
BMT-AO4
1108851302
1. Description
The BACnet MS/ TP module with 4 analog outputs was developed for decentralized switching tasks. It is suit able as encoder for
control variables, for example for elec trical vent and mixing valves,
valve positions, etc.
The outputs can be output by means of standard objects via a
BACnet client. T he module is addressed and the baud rate is set by
means of t wo addre ss switches on the front.
Suitable for decentralized mounting in serial sub- distributor.

6. Mounting
Power down the equipment
Mount the module on standard rail (TH35 per IEC 60715 in
junction boxes and/or on distribution panels).
Installation
Electric installation and device termination shall be done by qualifie d persons only, by re spec ting all ap plicab le
specifications and regulations.

The module can be aligned without interspace. Use the jumper
plug to connect bus and supply voltage when the modules are
mounted in series.
The max imum quan tity of m odules connec ted in line is limite d
to 15 or to a maximum power c onsumpt ion of 2 Amp s (AC or
DC) pe r connec tion to the power supply. For any similar b lock
of additional modules a se parate connect ion to the p ower
supply is mandatory.
7. Network adress and Bit rate setting
Configuration Switches
Hexadecimal Switches x10, x1 define the Network Address
(00 - F9; e.g. F9h = 15x16+9 = 249d) and Baud rate (FA – FF).
• Turn Switch x10 to E (Device is temporaryly configured as Slave)
• Turn Switch x1 to A – F to select Baud rate
• Turn Switch x10 to F, wait 1 second
• Red and green LEDs are blinking when Baud rate ist stored in
EEPROM
• Turn Switch x10 to select Network Address
• Turn Switch x1 to select Network Address
MS/ TP Master if using Network Address 0x00 … Max_Master,
MS/ TP Slave if using Network Address Max_Master + 1 … 0xF9.
