IRIG Input and Connections
The IRIG input is fully isolated and accepts a demodulated (dc level-shifted) signal. The input signal must
be 4.5 volts or higher to be recognized as a high logic level. Maximum input signal level is 25 volts. Input
burden is nonlinear and rated at 4 kΩ at 5 Vdc.
IRIG connections are located on a terminal clock shared with the RS-485 terminals. Terminal
designations and functions are shown in Table 7-4.
