IRIG Input and Connections
The IRIG input is fully isolated and supports IRIG Standard 200-98, Format B002. The demodulated (dc
level-shifted) input signal must be 3.5 volts or higher to be recognized as a high logic level. The maximum
acceptable input voltage range is +10 volts or –10 volts (a 20 volt range). Input burden is nonlinear and
rated at approximately 4 kΩ at 3.5 Vdc and approximately 3 kΩ at 20 Vdc.
IRIG connections are located on a terminal block shared with the RS-485 and input power terminals.
Terminal designations and functions are shown in Table 12-4.
