Connecting to a DVC5000f, DVC6000f, or DVC6200f Digital Valve Controller Connecting to a single instrument requires a fieldbus power hub (Relcom part number FCS-PH-110-PL, or equivalent). The power hub provides a power supply and double terminator. Up to four devices can be connected to the Relcom power hub. The computer with ValveLink Solo and NI-FBUS interface card is considered as one device. This product is used for bench testing. It is not designed for field applications.

Figure 10-6. Typical Connection to a DVC6000f Digital Valve Controller
If using a connection method other than the Relcom power hub, provide power using an approved fieldbus power conditioner in conjunction with a 24 VDC power supply. For more information on making connections to the digital valve controller, refer to the FIELDVUE DVC5000f Digital Valve Controller for FOUNDATION fieldbus instruction manual (D102634X012) (obsolete product), the DVC6000f Digital Valve Controller instruction manual (D103189X012) or the DVC6200f instruction manual (D103412X012).
Connecting the computer For a cable with connector: Step 1:
Connect pin 6 of the 9-pin connector to a power hub positive (+) connection.
Step 2:
Connect pin 7 to a power hub negative (−) connection.
Step 3:
Connect the cable shield to the power hub shield (S) connection.
To connect a twisted shielded pair cable: Step 1:
Connect one wire of the twisted pair to the D+ screw terminal on the PCMCIA-FBUS cable PORT 1.
Step 2:
Connect the other end of this same wire to the power hub positive (+) connection.
Step 3:
Connect the second wire to the D− screw terminal on the PCMCIA-FBUS cable PORT 1.
Step 4:
Connect the other end of this same wire to the power hub negative (−) connection.
Use twisted pair shielded cable to connect the instrument to the power hub. Step 5:
Remove the instrument terminal box cover.
Step 6:
Connect the instrument LOOP + terminal to the power hub positive (+) terminal.
Step 7:
Connect the instrument LOOP − terminal to the power hub negative (−) terminal.
Step 8:
Connect the shield to the power hub shield (S) terminal.
