Anville series 625 data acquisition system
The Anville Series 625 is a compact modular data acquisition unit, designed to provide accurate and reliable data measurement whilst operating in the harshest environments
Available in 8, 16 and 24 channel versions with analogue inputs, digital inputs analogue outputs (4 channels per slot) or digital outputs. All analogue input channels are individually configurable.
The unit features RS485 communications employing either MODBUS/RTU or ANSI-X3 protocols. TCP/IP MODBUS can be fitted as an option. An RS232 port is used for configuration.
Key features:
- Compact modular design
- Robust, rugged case with 3.5mm screw terminals
- Interchangeable cassette modules housing all active electronics
- Full inter-channel and system isolation (in comformance with EN60950)
- Individually configurable channels (scaling, features, etc.) through a simple setup utility
- Software configurable
