‑ Galvanic Isolation：Remote communication link provides electrical isolation between local rack and remote field side.
‑ Core Function：Remote I/O slave station management, Expander‑bus and remote serial link protocol conversion, remote I/O data forwarding, address configuration, link fault diagnosis, upload remote point data to DCS processor.
‑ Protection：Communication link surge protection.
‑ Status LED Indicators：Module run LED, fault LED, remote link status LED.
‑ Weight：approx 0.51kg
‑ IMRIO02 connects to MFP/BRC processor via Expander bus, works as remote I/O master node inside the rack, communicates with remote field I/O slave hardware through serial or fiber‑optic cable, realizes distributed remote I/O station expansion, reduce long‑distance field signal cable laying.
‑ Set station node address by onboard DIP switch; local mode and remote mode optional, single Expander bus supports up to 64 slave nodes, serial link supports maximum 16 remote dropsBailey Net….
‑ Support redundant configuration, two IMRIO02 modules form hot‑backup for remote I/O channel. Monitor remote communication link status; detect link break, module hardware fault, diagnostic alarm upload to operator station.
‑ Must install on Symphony Harmony standard rack, cannot run independently, must match MFP or BRC series processor, cooperate with NTRL02 fiber terminal unit when using optical fiber transmission.
Difference compared with ordinary local I/O module：IMRIO02 is communication expansion processor, not signal acquisition card; real field I/O channels locate on remote slave terminal units.
‑ Complete protocol conversion and data forwarding between Expander bus and remote I/O link.
‑ Monitor module hardware status and remote communication link quality, fault information upload to DCS system.
‑ No independent process control logic, all control algorithm executed by upper‑level station processor.
‑ Back‑plane：Rack internal Expander back‑plane bus for data exchange and module power supply.
‑ External interfaces：Remote serial communication port, match NTRL02 termination unit for fiber‑optic connection.
‑ Mounting：Plug‑in installation on Symphony Harmony standard rack
‑ Operating Temperature：‑20 ℃ ~ +60 ℃
‑ Storage Temperature：‑40 ℃ ~ +85 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Pollution degree：Degree 2
‑ Protection Class：IP20, cabinet‑internal installation.
- IMRIO02 remote I/O slave module（3BSE008586R1）
Complementary parts: Symphony Harmony rack, MFP / BRC series processor, NTRL02 fiber‑optic termination unit, NKLM01 communication cable, remote field I/O slave units, INFI‑NET network, operator & engineering station.
‑ Insert module into correct slot of Harmony rack, tighten front‑panel screws to guarantee reliable back‑plane connector contact.
‑ Set DIP switch node address strictly, address must be unique on Expander bus; redundant pair shall set identical node addressBailey Net….
‑ When adopt fiber‑optic transmission, configure NTRL02 terminal unit jumper correctly, fiber cable laying avoid squeezing and excessive bending.
‑ Recommend power‑off operation for module replacement. After replacement, verify Expander‑bus communication and remote I/O link status, check remote process point data collection.
