3.1.4. High Speed User Inputs 12-13 (J205)
The high-speed inputs shown in Figure 3-3, are scaled for a 5 volt input voltage. A
higher input voltage requires adding an external series resistor to limit the current to 7
milliamps. For example, 24 volt operation requires an external 2,700 ohm 1/2 watt
resistor in series with one of the input pins. The high-speed inputs (inputs 12 and 13)
have a delay of 50 nanoseconds (typical).
See Table 3-2 for the mating connector part number.

3.1.5. Analog Input 0 (J205)
The analog inputs accept a signal within the range of -10 t10 volts DC. Signals
outside this range may damage the input. For analog input technical information, see
Section 4.1.4.
