MOD 30ML Multiloop Controller
MODULAR I/O CONNECTIONS
4.3.7 2020N Remote I/O Interface Module (RIO) (discontinued)
Make remote I/O interface connections as shown in Figure 4-9. One remote I/O interface
module is required for each remote I/O network. The remote I/O interface module is scanned
every 50ms by the controller. A maximum of 2 RIO modules are allowed per instrument.
Specifications are:
REMOTE I/O INTERFACE RS485 SERIAL NETWORK
Bus Master 2020N Remote I/O Interface Module (end of bus)
Bus Slaves Remote I/O Digital Modules
Maximum Length 500 meters (1600 feet)
Baud rate 187.5K
Max addresses 32 (31 slaves + 1 RIO master at address 0)
Termination 120 ohm resister is required across the two conductors
at the end of the cable (2 shipped with RIO module)
Shield Required over 50 meters (160 feet)
REMOTE I/O INTERFACE CABLE
Indoor use Belden #9182
Indoor plenum use Belden #89182
Underground use Belden #9815 twisted twinax
Outdoors above ground use NOT recommended
Wiring Use same cable type throughout network. Avoid
interruptions (wire to same terminals if necessary).
Do not wire through terminal blocks.
