For those installations that support a fieldbus solution such as BACnet MS/TP, Contemporary Controls provides solutions for expanding the number of I/O points in the field. These compact cost-effective modules are available with analog and digital inputs and outputs in varying combinations.
BMT-DI4
The BACnet MS/TP module with 4 digital inputs was developed for
decentralized switching tasks. It is suitable for detecting potential-free
switch states, for example electrical limit switches on vent valves or
auxiliary contacts of power contactors. The inputs can be operated by
means of potential-free switches or contacts or used as voltage inputs.
The inputs can be scanned by means of standard objects via a BACnet
client. The module is addressed and the baud rate is set by means of
two address switches on the front.
BMT-DI10
The BACnet MS/TP module with 10 digital inputs was developed for
decentralized switching tasks. It is suitable for detecting potential-free
switch states, for example electrical limit switches on vent valves or auxiliary
contacts of power contactors. The inputs can be used as contact
or voltage inputs. The inputs can be scanned by means of standard
objects via a BACnet client. The module is addressed and the baud
rate is set by means of two address switches on the front.
BMT-SI4
The BACnet MS/TP module with 4 S0 inputs to DIN EN 62053-31
class A was developed for decentralized switching tasks. It is suitable
for counting S0 counter pulses. This allows very good integration of
the module into an energy controlling system. In case of a power
failure, the last counter readings are saved. The inputs can be scanned
by means of standard objects via a BACnet client. The module is
addressed and the baud rate is set by means of two address switches
on the front.
BMT-AI8
The BACnet MS/TP module with 8 individually configurable
resistance or voltage inputs is designed for local switching
operations. It is suitable to record resistance or voltage values of for
example passive and active temperature sensors electrical
ventilation or mixing valves, valve positions etc. The inputs are
universally configurable by standard object via a BACnet-Client.
Addressing of the module and baud rate setting are done with the
two address switches (x1 / x10) on the front. Possible settings are
addresses 00 to F9 and baud rates 9600 Bd, 19200 Bd, 38400 Bd,
57600, 76800 Bd and 115200 Bd.
BMT-DO4
The BACnet MS/TP module with 4 digital outputs is designed for
local switching operations. It is suitable to operate electrical
components such as motors, contactors, lamps, sun-blinds etc. We
recommend to protect the relay contacts additionally by a
RC-element or high inductive loads. The module is provided with
a manual control facility for manual switching of the relays. The
outputs can be operated by standard objects via a BACnet-Client.

BMT-AO4
The BACnet MS/TP module with 4 analog outputs was developed
for decentralized switching tasks. It is suitable as encoder for
control variables, for example for electrical vent and mixing valves,
valve positions, etc. The outputs can be output by means of standard objects via a
BACnet client. The module is addressed and the baud rate is set by
means of two address switches on the front.
BMT-DIO4/2
The BACnet MS/TP module with 4 digital inputs and 2 relay
outputs with manual control was developed for decentralized
switching tasks. It is suitable for accommodating, for example,
light switches and window contacts in a room, switching two light
strips or controlling louvers. It can also be used to control 2 motorized
fire dampers. With strong inductive loads, we recommend
protecting the relay contacts with an RC element. The inputs can
be used as contact or voltage inputs. The inputs and outputs can
be switched and scanned by means of standard objects via a BACnet
client. The module address and the baud rate are set by means
of two address switches on the front.
NG-4 Gray
The NG4 power supply supplies regulated direct voltages for
supplying power to the respective devices of the product family of I/O
components. The device supplies regulated direct voltage 24 V DC at
a power of 16 watts. A parallel operation of several power supply units
is not allowed. The secondary voltage can only be tapped at the right
side of the plug connector and at the screw-type terminals on the top
of the module. The bus communication is looped through on both
sides of the plug connectors.
