- Dual Channel, Compact Size: The module offers two sensor input channels in a 3U, 1-slot plug-in format, reducing cabinet space by half compared to traditional modules.
- Supported Sensors: Eddy-current, piezoelectric (accelerometer or velometer), seismic (electro dynamic), low-frequency bearing vibration, Hall-effect, and LVDT sensors (with A6500-LC).
- Signal Range and Accuracy: Voltage ranges from ±1 V to ±23 V depending on sensor type, with frequency response up to 18,750 Hz; attenuation typically <0.1 dB.
- Digital I/O: 5 digital inputs, 6 digital outputs including solid-state relays with protection against polarity reversal.
- Self-Checking: Includes hardware, power input, temperature, sensor, and cable diagnostics to enhance reliability.
- Communication: Uses RS485 bus to A6500-CC Com Card with data transmission in Modbus RTU and TCP/IP protocols.
- Analog Outputs: Front and rear buffered, and proportional 0/4–20 mA outputs with common ground and electrical isolation.
- Supply Voltage: -23.25 V to -26.0 V DC, short circuit proof with 35 mA max load.
- Robust Environment Support: Operating temperature from -20 °C to +70 °C; storage -40 °C to +85 °C; IP20 protection; resistance to airborne contaminants per ISA-S71.04-G3.
- Compliance: Meets API 670 machinery protection standards, suitable for critical control systems.
