Time-Code Input Relay module accepts demodulated IRIG-B time-code input at Port 1 and Port 2
(Port 1 is an optional EIA-485 port). Do not connect the time-code input into both
Port 1 and Port 2 at the same time. Relay time is synchronized to within
±
5 ms of
time-source input.
Serial
Communications
Two side-panel and one front-panel EIA-232 serial communications ports.
One optional side panel EIA-485 serial port with 2100 Vdc of isolation.
Per-port baud rate selections: 300, 1200, 2400, 4800, 9600, 19200, 38400.
Routine Dielectric
Test
Control ac power: 2500 Vac for 10 seconds.
Optoisolated inputs, analog inputs, and output contacts except Trip and Close:
3100 Vdc for 10 seconds.
