Table 1 lists the terminal assignments for the signals of each
channel. Terminal assignments are also listed on the side panel
of the cFP-PG-522 and under the slide-in card on the front of the
FP-PG-522.
Pulse Output Circuit
The [c]FP-PG-522 output channels are optically isolated from the
rest of the FieldPoint bank. In the ON state, a transistor is turned
on between the output (V
OUT
) and common (C and COM). In the
OFF state, this transistor is turned off, allowing only a small
leakage current to flow.
Ensure that the load on any channel does not draw more than 2 A.
In addition, the sum of the squares of the channel currents must
not exceed 16 A

. For example, five channels operating at 1.2 A
yields 7.2 A

:
(1.2 A)

× 5 = 7.2 A

Caution For a cFP-PG-522 operating in the 60–70 °C
temperature range, the sum of the squares of the channel
currents must not exceed 8 A
