TECHNICAL DATA
Power
24VAC power from a UL Listed Class-2 24VAC transformer
(not provided). The BACnet FF uses a half-wave rectifier
to convert the AC power supply to onboard power. This
enables multiple devices with half-wave power supplies
to be powered from a single, grounded transformer.
Min. Load = 17VA (all BOs OFF).
Max. Load = 89VA (all BOs ON).
If BO power jumper is not removed, then all BOs are pow-
ered from the controller’s transformer.
Minimum load includes controller and analog outputs at
full load (20mA into 500 Ohms).
All BOs are N.O. (Normally Open) contacts with a maxi-
mum switch rating of 24VAC @ 0.5A (12VA).
Maximum load assumes all 6 relay output loads are pow-
ered from the controller transformer and connected
loads are the maximum allowed (24VAC @ 0.5A). Actual
power requirements depend on connected loads.
Wireless Receiver (TB3026B-W only)
433.92 Mhz; range is 50 feet.
Inputs
3 universal inputs with 12-bit accuracy, providing con-
trolled voltage, current and resistive modes.
Internal Sensors
1 internal temperature sensor, 0–120 deg. F (-17.8–48.9
deg. C); 1 internal humidity, 5–95% RH, non-condens-
ing.
Relay Outputs
6 relay outputs; normally open contacts with a maximum
switch rating of 24VAC @ 0.5A (12VA). BO-0, BO-2 and
BO-5 are powered from the controller transformer. BO-
1, BO-3 and BO-4 are powered from control trans-
former through removable jumper, allowing these BOs
to be powered from a separate power source.
Universal Analog Outputs
2 outputs with 12-bit resolution. Each auto-detects for 0–
10VDC or 4–20mA. 4–20mA outputs are sourced by the
VLD. Connected loads must return to the VLD ground.
The BACnet FF automatically switches from 0–10V
mode to 4–20mA current mode when it detects a load
value of less than 500 Ohms.
Processor & Memory
Powerful 32-bit processor with extensive flash memory
and RAM resources. Flash memory provides nonvola-
tile program and data storage, and allows for encrypted
updates to the program for future product enhance-
ments.
Environmental
Residential, commercial and light-industrial environ-
ments. 0–120 deg. F (-17–49 deg. C). 0–95% RH, non-
condensing.
Communications
BACnet MS/TP LAN up to 76.8Kbps.
Ratings
Listed Underwriters Laboratory for Open Energy Manage-
ment Equipment (PAZX) under the UL Standard for
Safety 916; listing includes both U.S. and Canadian
certification.
EMC Directive (European CE Mark) EN 60950 (VLD-362-
FF model only).
FCC Part 15, Class B.
