Reference Data
These graphs are based on actual measured values sampled from the production
line. Treat the data as reference values because there is some variation
in relay characteristics.
The following graphs show the characteristics for G6D-1A Relays installed in
SRT1-ROC08 and SRT1-ROC16 Relay-mounted Remote Terminals.
