Temperature/Voltage de-rating curve
Electrical and Environmental Specifications
The SPX-1300 units should be operated with a filtered 12 Volt nominal DC supply. "
However, any voltage between 8 and 16 volts can be utilized by following the temperature /voltage derating curve.
Voltage should not exceed 16 VDC."
"
Digital Data (D0/D1) Inputs and Outputs are OpenCollector with switchable 1k pullup resistors.."
"
Data I/O Points are rated for the following voltages:"
0 - 5 VDC with pullups on "
0- 24 VDC with pullups off"
"
All Digital Inputs and Outputs are 0 - 24 VDC tolerant . Pullup resistors should be disabled when using I/O at voltages
greater than 5VDC to prevent excessive current draw and possible component damage. "
"
Analog Inputs are rated for 5 VDC max."
The Relay 3, Relay 4 inputs and Programming resistor inputs are analog inputs and are limited to 5 volts DC Maximum."
"
All inputs and outputs are provided with transient and static protection."
"
The RS-485 communication channel will provide the best performance using shielded twisted pair wiring. Other wire
types can be used, and performance will depend upon actual field conditions. The Suprex units will typically function
with: Coax, THHN building wire, Cat5 and Cat 3 cable, etc.

"
When the Suprex units are operating correctly and have a valid communication channel between"
the Remote and Central units the Diagnostic indicators on each unit will flash green rapidly "
(2-3 flashed per second)."
"
If the units are not communicating, viewing the diagnostic indicator LED’s may help to determine
the "
nature of the problem."
"
DIAGNOSTIC LED NOT ILLUMINATED:"
"
If the LED(s) are not illuminated on the unit(s) then the unit is not getting power. The Diagnostic
LED’s"
will be illuminated when power is applied."
"
CENTRAL UNIT FLASHING BETWEEN RED/GREEN:"
"
With power applied and no communication path between the Remote and Central, the Central
unit will flash the diagnostic indicator alternately between Red and Green."
"
REMOTE UNIT ILLUMINATED RED:"
"
The Remote unit will diagnostic LED will illuminate solid (not flashing) red if it is not receiving
communication from the Central."
"
REMOTE AND CENTRAL UNITS FLASHING BETWEEN RED/GREEN:"
"
The Central is not Receiving communication from the Remote.
