POWER SUPPLY REQUIREMENTS
Primary Electronics re24 VDC for operation. An AC-DC converter external power supply
rated at 24VDC nominal, 2.7A maximum, complying with IEC/UL 60950-1 2nd Ed.+Am1 and
evaluated to clause 2.5 (LPS) of the mentioned standards is required.
+24 VDC is supplied though power connector J18 or J31.
The pin assignments for the power connector are as follows:
PIN #
SIGNAL
1
+24V RTN
2
GND
3
+24V
Table 1: Power Connector Pin Assignments
The input +24V is converted to +12V, +5V, +3.3V, +2.5V and +1.2V through DC-DC converters
integrated within the PCB circuitry. Both switch mode and linear regulators are used.
