SmartSensor Matrix
The input le cards shall be compatible with 170, 2070,
NEMA TS 1, and NEMA TS 2 style input racks.
The input le card shall translate data packets from the
RPD into contact closure outputs.
The input le card shall support presence detection.
The input le card shall receive data packets over an RS-
485 bus at a baud rate of 9600 bps.
The input le card shall autobaud and auto-detect an RPD
over wired and wireless communication channels that
have a maximum latency of 500 ms.
The input le card shall comply with the NEMA TS 2-1998
Trac Controller Assemblies with NTCIP Requirements
(Section 2.8 specication).
2.4 In Cabinet Interface Equipment. The RPD shall be
installed using the SmartSensor Matrix Preassembled
Trac Cabinet Backplate or an equivalent that provides
input power surge suppression, sensor cable surge sup-
pression, AC to DC power conversion (if necessary), and
terminal blocks. The surge protection devices shall meet
or exceed the EN 61000-4-5 Class 4 specications.
2.5 Power Supply. If needed, the RPD shall be installed
using the Click!™ 202, Click! 204 or an equivalent AC to
DC power converter that meets the following specica-
tions:
The power converter shall be power rated at 48 W for tem-
peratures less than 140°F (60°C) with a 5% power decrease
for each degree increase up to 158°F (70°C).
The power converter shall operate in the temperature
range of to -29.2°F to 165.2°F (–34°C to 74°C).
The power converter shall operate in the humidity range
of 5% to 95% at 77°F (25°C) non-condensing.
The power converter shall accept an input voltage of 85 to
264 VAC or 120 to 370 VDC.
The power converter shall operate at an input frequency
of 47 Hz to 63 Hz.
The power converter shall produce an output voltage of
24 VDC ±4%.
The power converter shall withstand a voltage across its
input and output of 2 kV. The power converter shall with-
stand a voltage across its input and ground of 1.5 kV.
The power converter shall conform to safety standards
UL 60950 and EN 60950.
The power converter shall conform to EMC standards EN
55022 Class B and EN 61000-3-2, 3.
In brown-out conditions (i.e. < 85 VAC input), the output
voltage of the power converter shall be less than 1 VDC.
The terminal blocks shall be color-coded insulation dis-
placement terminal blocks.
The terminal blocks shall be prewired to the other in-
cabinet equipment so that no wiring other than cable ter-
minations, connecting input power and connecting input
le cards shall be required during installation.
2.6 Input File Cards. The Click! 114, Click! 112 or an
equivalent that meets the following specications shall be
used.
