Technical Insights
16‑Channel Galvanic Isolation
Isolation protects the control system from field wiring faults and dangerous voltage surges on site.
This design greatly improves system safety and stability in noisy industrial environments with heavy machinery.
It also ensures accurate signal measurement even when multiple sensors operate in the same area.
High Measurement Accuracy & Resolution
High precision ensures reliable process data for pressure, temperature, flow, and level monitoring systems.
Accurate readings reduce false alarms and help operators make correct decisions in real time.
This performance directly improves the effectiveness of safety and predictive maintenance strategies.
Wide Environmental & Safety Compatibility
It supports IEC 61508 SIL 3 safety standards for use in the most critical safety instrumented systems.
Strong environmental resistance extends module life and reduces failure rates in demanding field conditions.
It meets global certification requirements for use in hazardous and industrial areas worldwide.
Installation & Maintenance
Correct Slot & Wiring Installation
Always power off the entire rack before inserting or removing the module to avoid electrical damage.
Route sensor cables separately from high‑voltage power lines to reduce electromagnetic interference.
Channel Configuration Best Practices
Verify input ranges before operation to prevent over‑range errors and module damage.
Label each channel clearly on the wiring panel to simplify future maintenance and troubleshooting.
Routine Diagnostic Inspection
Review per‑channel diagnostic data monthly to detect open circuits, short circuits, or signal drift early.
Clean dust from the rack quarterly to improve cooling and maintain stable module performance.
