MDC-260 DEPOSITION CONTROLLER
INPUT/OUTPUT CHARACTERISTICS 7-2
The Passive inputs are activated by shorting the input’s pins together. The inputs
are internally pulled up to 5 volt through a 4.7 Kohm resistor and incorporate a
10-millisecond filter to enhance noise immunity and provide protection from a
momentary short. The Passive input circuit is shown in Figure 7-1.
The Active inputs are activated by supplying 12 to 120 volt AC or DC across the
input pins. The inputs incorporate a 10 millisecond filter to enhance noise
immunity and provide protection from a momentary short. The Active input
circuit is shown in Figure 7-2.
Pin assignments are shown in Table 8-2.
