Terminals CAC1 and CAC2 for future use
4-20 mA Terminal Block
4-20 mA In A+ (INA+)
4-20 mA In A- (INA-)
1000 feet maximum length
Use Belden 9535, 2-conductor, 100% shield coverage, 300V 80C (UL 2464, CSA PCC FT 4) or equivalent.
Notes on shield wire termination: The shield wire should be grounded immediately as it enters the enclosure that
houses the MRV Interface Panel. If the Interface Panel is purchased with the enclosure option, terminate the shield
wire on the corner ground post closest to where the cable enters.
4-20 mA In B+ (INB+)
4-20 mA In B- (INB-)
Terminal INB+ and INB- for future use
4-20 mA Out+ (OUT+)
4-20 mA Out- (OUT-)
1000 feet maximum length
Use Belden 9535, 2-conductor, 100% shield coverage, 300V 80C (UL 2464, CSA PCC FT 4) or equivalent
Notes on shield wire termination: The shield wire should be terminated at the process controller end only, not at the
Interface Panel enclosure.
Network Interface Terminal Connectors
Valve-0:
Field 24VDC Power (F24+)
Field 24VDC Common (F24-)
Data A (DA)
Data B (DB)
100 feet max length to each actuator; 1000 feet maximum to optional remote User Display
EIA Level 4 cable, 2 twisted pair with shield, 22 AWG
Cable sources:
MAXON - P/N 59829 (available in 100 and 500 ft. lengths)
Connect-Air International P/N W22P-1005
Suggested wiring color code convention:
Orange/White (F24+), Orange (F24-), Blue (DA), Blue/White (DB)
300 feet max length to each actuator with Belden P/N 3086A: 2 twisted pair with shield; 16 AWG - power pair, 20 AWG
- data pair
Suggested wiring color code convention: Brown (F24), Blue (FCOM), White (DA), Black (DB)
Notes on shield wire terminations:
The shield wire of each actuator network cable should be connected to the actuator "SHD" terminal (keeping the shield
length to 1 inch or less). In addition, the shield wire should be tied to ground as it enters the enclosure of the MRV
Interface Panel (keeping the maximum length to 2 inches or less). If the Interface Panel is purchased with the enclo-
sure option, terminate the shield wire on the corner ground post closest to where the cable enters the enclosure.
