AKCP 4-20mA Signal Converter (VC00)

Analog 4-20mA sensors have been a standard in industrial measurement and control technology for decades. With the AKCP 4-20mA Signal Converter (model VC00), these classic sensor technologies can be easily integrated into modern network-based monitoring platforms. This allows companies to continue using existing measurement infrastructures while benefiting from digital SNMP monitoring.

Function and Application Benefits

The converter transforms the 4–20 mA signal current into a 0.8–4.0 V voltage signal, which can be precisely measured by sensorProbe and securityProbe systems. This enables seamless data collection and analysis that was previously limited to purely analog visualization.

Supported Sensors

The interface supports connection of virtually all common industrial analog sensors:

• Pressure sensors and differential pressure sensors
• Flow sensors and flow meters
• CO₂ and gas sensors
• pH measurement probes
• Temperature sensors and strain gauges
• Custom special transducers with 4-20mA output

Technical Highlights

• Input signal: 4-20 mA (standard current loop)
• Output: 0.8 – 4.0 V (voltage)
• Linearity: ±0.09%
• Measurement accuracy: ±0.15%
• Power consumption: 120 mW / 24 mA
• Power supply: via AKCP sensor controller (5 V DC)
• Operating temperature: –40 °C to +85 °C
• Dimensions: 65 × 62 × 15 mm
• Mounting: DIN rail or screw fixing
• Max. cable length: 15 m (Cat5/6 UTP)

Easy Installation and Integration

Installation requires no complex configuration:

• RJ45 connection to sensorProbe+/securityProbe systems
• AutoSense: automatic detection and configuration of the converter
• Direct access to sensor data via the web interface
• Easy calibration according to measurement ranges

Alerts and Data Management

Configuring individual alarm thresholds enables proactive maintenance. Signal deviations can be reported via:

• Email
• SMS or MMS (with GSM/LTE gateway)
• SNMP traps

Measured values can also be exported for historical analysis and integrated into long-term reports and energy/process evaluations.

Compatibility

The converter is fully compatible with AKCP sensorProbe+ and securityProbe alarm servers. Via SNMP OIDs, values can be centrally integrated into leading NMS systems, including Nagios, OpenNMS, Zabbix, PRTG, and IBM Tivoli.

Typical Applications

• Industrial automation: integration of existing pressure, flow, and level sensors
• Energy: monitoring consumption in supply networks
• Building services/HVAC: integration of analog climate and ventilation sensors
• Data centers: connecting custom measurement modules to AKCP infrastructure
• R&D: flexible integration of scientific sensors
