34 Common
34 Common
The Relay Common, pin 34, on the I/O Amp Champ
™
connectors, P1 and P3, is
shipped with no connection to either Power Ground nor the Discrete Input
Common. This was engineered to prevent ground currents and to allow the user
to set each eight-block set of Relay Commons as they require. If desired the
Relay Common can be connected to the Discrete Input Common by installing a
jumper as shown in Figure 3 (jumper labeled P1).
Figure 4 shows the SW2 dip switch settings which are used for the I/O module
board address based on the position of the I/O board within the RTU chassis.
