Functional Characteristics

• 15-Channel Density: 15 single-ended channels maximize I/O coverage for cost-efficient current signal monitoring.
• Jumper Configuration: Carrier jumper selects 4-20 mA or 0-20 mA input range, no manual per-channel settings.
• Software Flexibility: Supports default/hold last state operation via software for error handling.
• Optical Isolation: 250 VAC continuous, 1500 VAC for 1 minute isolation protects logic circuits from field-side noise and surges.
• Open Wire Detection: Detects open circuits in 4-20 mA mode, reporting to CPU for HMI/SCADA alerts.
• Backplane Power: No external power supply needed, simplifying installation and reducing wiring.
• Onboard Diagnostics: Reports loss of internal power and A/D conversion malfunctions, with LED status indication for quick troubleshooting.
• Fast Update Rate: 7.5 ms per module ensures real-time responsiveness to dynamic process changes.

Application Scenarios

• Process Control: Oil refineries, chemical plants, and water treatment facilities for pressure, temperature, flow, and level monitoring with 4-20 mA transmitters.
• Manufacturing Automation: Assembly lines and machine tools connecting flow meters, pressure transducers, and load cells to PLCs for closed-loop control.
• Building Automation: HVAC systems monitoring air handlers, chillers, and VFDs with 4-20 mA sensors.
• Energy Management: Power generation/distribution for transformer 油温，generator output, and grid parameter monitoring via current sensors.
• Test & Measurement: Lab and production line testing requiring high-channel-count current data logging with 15-bit precision.
• Remote SCADA: Unattended sites with VersaMax PLCs, leveraging backplane power, open wire detection, and diagnostics for reliable long-term operation.
