‑ IMCIS02 is multi‑function compound I/O module, integrates multiple AI/AO/DI/DO channels in one single card. Realizes field process variable collection and control command output.
‑ Analog input acquires voltage and current process signals; analog output outputs 4‑20mA / voltage control signal to field actuators. Digital input detects equipment status feedback; digital output drives field relay and solenoid valves.
‑ Built‑in comprehensive self‑diagnosis function: detect channel open circuit, over‑range, output short‑circuit, module hardware failure, fault alarm information upload to DCS operator station.
‑ Installed on Symphony Harmony standard rack, must match supporting terminal unit for field signal wiring, cannot work independently.
Difference compared with IMCIS22：IMCIS02 is early‑generation control I/O module; IMCIS22 is upgraded revised version with improved precision and driving capacity.
‑ Collect field analog and digital signals, transmit data to upper‑level BRC controller.
‑ Receive control commands from controller, convert and output analog and digital control signals to field side.
‑ Complete channel diagnosis, fault status uploaded to DCS system.
‑ No local logic operation function, all control logic executed by BRC bridge controller.
‑ Back‑plane：Rack internal back‑plane bus for data communication and module power supply.
‑ External interfaces：Connect field transmitters, actuators and auxiliary equipment by matching terminal base unit.
‑ Mounting：Plug‑in installation on Symphony Harmony standard rack
‑ Operating Temperature：‑10 ℃ ~ +60 ℃
‑ Storage Temperature：‑20 ℃ ~ +70 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Pollution degree：Degree 2
‑ Protection Class：IP20, cabinet‑internal installation.
- IMCIS02 control I/O module（3BSE008578R1）
Complementary parts: Symphony Harmony rack, matched terminal unit, BRC series bridge controller, system power supply, field transmitters, actuators, relay components.
‑ Insert module into correct slot of Harmony rack, ensure reliable back‑plane connector contact.
‑ Field signal wiring must use supporting terminal unit, strictly distinguish analog input, analog output, digital input and digital output signal terminals, prevent mis‑wiring causing module damage.
‑ It is recommended to replace module under power‑off condition. After replacement, download corresponding channel configuration, verify signal acquisition and control output function.
‑ Pay attention to output load limit, do not exceed module maximum driving current.
