PFC-6075R • 5403594 • REV D • 9/14
Input Circuits
The panel is equipped with two (2) input circuits, I1 and I2, that are low voltage, power limited, and supervised. When
configured, the circuits function as dry-contact monitoring circuits.
Note: These circuits operate as Class B only. Please refer to the figure shown below.
Configuration Characteristics
• Maximum allowable wire length is 10,000 feet.
• Maximum allowable wiring resistance is 100 ohms.
• Maximum wiring capacitance is 1 uF.
• Maximum IDC voltage is 24 VDC, and current is 15 ma.

Notes:
1. The Potter part number for the listed end of line assembly is #3005013 EOL Resistor Assembly.
2. The panel has ground fault detection on the input circuits. The impedance to ground for ground fault detection is 0 ohms.
3. The end of line resistor is a 5.1K ohm resistor.
Wiring to Control Panel
The control panel communicates with and supervises the PSN-1000/PSN-1000(E) via the main P-Link circuit. This connection
is electrically isolated from the rest of the PSN-1000/PSN-1000(E).
