Stacked System and Sensor Bus Terminal Block

A dual-stacked connector serves as the system bus and sensor bus port on the Verasys Controllers. The upper row 
on the connector is the system bus port. The lower connector row is the sensor bus port.

Figure 5:  Stacked System and Sensor Bus Terminal Block 

System Bus Terminal Block

The System Bus terminal block is a blue, removable, 4-terminal plug that fits into a board-mounted jack. Wire the 
removable system bus terminal block plugs on the controller on the top row of the stacked connector. Wire the other 
field controllers in a daisy-chain configuration using 3-wire twisted, shielded cable, as shown in the following figure. 
See Table 7

 

for more information on functions, ratings, requirements and cables.

Figure 6:  System Bus Terminal Block Wiring   

Note:

The System Bus Shield (SHD) terminal is isolated and you can use it to connect the shields, in a daisy-

chain configuration for system bus wiring.

Sensor Bus Terminal Block

The Sensor Bus terminal block is a brown, removable, 4-terminal plug that fits into a board-mounted jack.
