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.

•
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:
The Potter part number for the listed end of line assembly is #3005013 eOL Resistor Assembly.
1.
The panel has ground fault detection on the input circuits. The impedance to ground for ground fault detection is 0 ohms.
2.
The end of line resistor is a 5.1K ohm resistor.
3.
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).
