Technical Specifications Supply voltage DC 24V, power consumption 7.2W. Operating temperature range ‑40℃ ~ +70℃, relative humidity 5%‑95% non‑condensing. Standard I/A rack plug‑in card form factor, IP20 protection level. Backplane bus communication rate compliant with I/A series internal bus protocol.
Functional Features Multi‑channel signal acquisition and output processing. On‑board LED status indicators for channel and module health status. Support backplane bus real‑time data interaction. Built‑in signal filtering circuit to suppress industrial electromagnetic interference. Allow hot‑swap under valid system configuration conditions. Support channel fault diagnosis.
Application Scenarios Petrochemical plant DCS control, chemical production process monitoring, thermal power auxiliary control system, metallurgical process automation, water treatment automatic control, oil & gas processing plant control cabinet.
Performance Parameters Signal processing resolution 16‑bit. Channel response time less than 120ms. Meet continuous long‑time running requirement for industrial sites. MTBF conforms to Foxboro industrial control component standard.
Structural Characteristics Plug‑in circuit board structure matching I/A series rack. Front panel with LED indicator group. Gold‑plated backplane contact pins for reliable connection. Mechanical locking buckle to prevent loosening caused by vibration.
Working Principle Field analog or digital signals enter the module, pass through signal conditioning and isolation circuit, convert into digital data and upload to controller via back‑plane bus. Received control commands from controller are converted into corresponding output signals to drive field equipment.
Installation Requirements Mount module in designated slot of standard I/A series rack. Ensure back‑plane connectors are clean and fully inserted. Verify cabinet power supply meets DC24V requirement. Keep cabinet good ventilation, avoid high‑temperature and damp installation position. Keep away from high‑voltage cables.
Usage Notes Power shall be checked before installation. Do not touch gold‑plated contacts directly. Follow system operation specification for hot‑swap. Inspect LED indicator regularly. Avoid corrosive gas, dust and strong vibration environment.
