Table 13 1764-28BXB FET Output Specifications
Specification General Operation
(Outputs 2 thru 7)
High Speed Operation
(1)
(Outputs 2 and 3 Only)
(1) Outputs 2 and 3 are designed to provide increased functionality over the other FET outputs (4 through 7).
They may be used like the other FET transistor outputs, but in addition, within a limited current range, they
may be operated at a higher speed. Outputs 2 and 3 also provide a pulse train output (PTO) or pulse width
modulation output (PWM) function.
