I/O Flex 6126 Controller Specifications
POWER
24 vac ± 10%, 50 to 60 Hz, 20 va power consumption (26 va with
BACview tool attached):
26 Vdc (25 V min, 30 V max)
Single Class II 100 va or less
PHYSICAL
Rugged aluminum housing, removable screw terminals with cus-
tom silk-screening available.
ENVIRONMENTAL OPERATING RANGE
–20 to 140°F (–29 to 60°C), 10 to 95% relative humidity, non-
condensing.
DIGITAL OUTPUTS
6 binary outputs relay contacts rated at 5A max at 250 VAC. Con-
figured normally open or normally closed.
ANALOG OUTPUTS
6 analog outputs, 1 and 2 are configurable for 0 to 10V or 0 to
20mA; 3 through 6 are 0 to 10V only.
UNIVERSAL INPUTS
12 universal inputs are used to monitor input from various sensors.
These universal inputs can be set for one of three different sensor
input types:
1. Voltage (0 to 10 V),
2. Temperature (resistance temperature detector or thermistor)
or discrete contact, or
3. Current (0 to 20 mA).
Inputs 1 and 2 may be used for pulse counting.
STANDARD COMMUNICATION PORTS
Comm Port:
P1: Communication with the ARC156 networks
P2a: Configurable for EIA-232 or EIA-485 (2 wire or 4 wire).
Network protocol selectable for BACnet (MS/TP or PTP), Mod-
bus, N2, LonWorks SLTA, or modem.
P2b: Configurable for LonWorks plug-in or Ethernet.
RNET PORT
Supports up to four RS Standard sensors and one RS Plus, RS Pro
for averaging or high/low select control. The sensors can share the
Rnet port with BACview.
LOCAL ACCESS PORT
For local communication with a laptop computer running virtu-
al BACview.
XNET PORT
For communication with the I/O Flex EX8160 expander.
BACNET 1 SUPPORT
Conforms to the Advanced Application Controller (B-AAC)
Standard Device Profile as defined in ANSI/ASHRAE Standard
135-2004 (BACnet) Annex L.
STATUS INDICATION
Visual (LED) status of network communication, running, errors,
power, transmit/receive for Port 1 and Port 2a and for each of the
12 outputs.
1.BACnet is a registered trademark of ASHRAE.
BATTERY
10-year Lithium 3 v coin cell battery, CR2032, provides a mini-
mum of 10,000 hours of data retention during power outages.
PROTECTION
Incoming power and network connections are protected by non-
replaceable internal solid-state polyswitches that reset themselves
when the condition that causes a fault returns to normal. The pow-
er, network, input, and output connections are also protected
against voltage transient and surge events.
LISTED BY
UL-916 (PAZX), CUL-916 (PAZX7), FCC Part 15-Subpart B-
Class A, CE EN50082-1997.
WEIGHT

4
depth). 127 mm (width) by 299 mm (height) by 51 mm (recom-
mended panel depth).
MOUNTING HOLE DIMENSIONS
Four mounting holes, two above and below.
Width: 4 in. (102 mm)
Height: 11 3 / in. (289 mm)

Addressing the I/O Flex 6126 Controller
The I/O Flex 6126 controller's two rotary switches determine the
I/O Flex 6126 controller's MAC address when it is placed on a
BACnet/ARC 156 or BACnet MS/TP network. The rotary switch-
es define the MAC address portion of the device's BACnet ad-
dress, which is composed of the network address and the MAC
address. They also set the slave address on a Modbus or N2 net-
work, when less than 100.
If the I/O Flex 6126 controller has been wired for power, when
changing its address in the field the power switch must be cycled
or the screw terminal connector from its power terminals labeled
Gnd and Hot. The controller reads the address each time power is
applied to it.
Using the rotary switches; set the controller's address. Set the Tens
(10's) switch to the tens digit of the address, and set the Ones (1's)
switch to the ones digit. See Fig. 28.
EXAMPLE: If the controller's address is 01, point the arrow on
the Tens (10's) switch to 0 and the arrow on the Ones (1's) switch
to 1.

NOTE: The I/O Flex 6126 controller recognizes its address only
after power has been cycled.
BACnet Protocol Selection
50BV VAV controllers are capable of both BACnet ARCnet and
MS/TP. The factory default is ARCnet. To change to MS/TP, us-
ing the Virtual BACview interface, press FN + 0 to go to the net-
work screen. Change the "+' symbol from ARCnet to MS/TP, us-
ing the arrow keys and soft keys to make the change.
