Transmitter Outputs
Voltage Output
Re-transmitted from module.
Voltage Range:
0-5V, equivalent to the microBlox® module output
retransmitted at the carrier output ±voltage terminals TB4.
Voltage Load:
5V into 1KΩ minimum, or 5mA Maximum.
Accuracy:
±0.05% of span typical (from module), or ±0.1% of 5V span, ±5mV
maximum (module in carrier). Refer to your module specifications for details.
Current Output
Derived from plug-in module and
transmitted from carrier.
Current Range:
0-20mA/0-5V, 4-20mA/1-5V, output current and current return
at TB4.
Note for 4-20mA Current Output
: The alarm carrier normally requires that
input modules scale their input to 0-5V output for use on this carrier, which also
produces 0-
20mA at the carrier’s current output. If your application requires a
4-20mA current output instead of 0-20mA, you may use the I/O scaling function
of the Agility mobile app to scale your module’s input range to 1
-5V output
instead of 0-5V, to produce 4-20mA from the alarm carrier (note the tandem
voltage output of the carrier also becomes 1-5V, not 0-5V). The App will also
scale for you if you select 4-20mA as an output type option under the uBTA
Alarm tab (which also sets the voltage output to 1-5V).
Output Maximum:
24mA typical.
Load Resistance:
0-
550Ω minimum (20mA).
Accuracy:
±0.1% of 20mA span, or ±0.020mA maximum.
Current Trim:
±0.08mA adjustable via a precision 15 turn Trim Pot near the
output terminals. Adjustment is not normally required, but useful for making
fine output current adjustments or to correct for component aging at the
channel (See Output Current Trim adjustment for instructions on making this
calibration).
Controls
The LED indicators are located on the front-panel adjacent to the module socket.
The CJC and BLE jumpers are wired between TB1 and TB2 terminals.
LED Indicators (front-panel)
PWR (Green) -
ON indicates power is applied to carrier and the uB module is
operating normally (sourced by 3.3V from module).
BLE (Blue)
–
ON indicates Linking to module is enabled (requires BLE jumper,
sourced by 3.3V from module).
Relay 1 & Relay 2 (Orange) -
ON indicates corresponding relay is energized.
BLE Jumper
(Install at TB2)
Install a jumper between the first two terminals of TB2 to allow a Bluetooth
wireless technology link to the module to accomplish alarm reconfiguration.
CJC Jumper
(Install at TB1)
Install a jumper between the last two terminals of TB1 to make a CJC
connection. Some modules require this jumper to be installed or removed
depending on the model per below (also consult specific module instructions).
