Safety Consideration When Configuring Relays
It is important to configure relays correctly to ensure that one circuit fault affects no
more than two channels.
Each relay module consists of eight processors and each processor controls four relays.
When configuring a redundant relay setup, select relays of different processors.
For example, use relay 1 and relay 5 to ensure that one circuit fault does not affect both
relays. See the table below for details of relay assignments.
Table 2-5: Relay assignments.
