Basic Information
Weight:Approximately 450g
Dimensions:241.3mm×24.4mm×99.1mm
Origin:USA
Features
Input and Output Configuration:Provides four sensor inputs and four temperature inputs.The sensor inputs support 2-wire and 3-wire accelerometers,velocity sensors,or proximity sensors.Each temperature input supports E,J,K,and T-type thermocouples,as well as 2-wire or 3-wire RTDs.Also provided are six relay outputs,four 4-20mA recorder outputs,and one dedicated buffered output.
Communications:Supports Modbus communication via Ethernet and a software-configurable RS232/485 serial port.A Modbus gateway option allows the monitor to directly provide static variables,status,event lists,and time and date information to any Modbus client.Configurability:Users can create configuration files using 1900 Configuration Software and download them to the monitor via the built-in Ethernet connection,defining monitor operation and Modbus gateway register mapping.An optional display/keyboard is also supported for viewing channel information or making minor configuration changes.
High-Precision Measurement:Utilizing a 24-bit ADC with configurable scale factors and full-scale ranges,the monitor offers alarm accuracy within 0.13%of the desired value and a direct signal frequency response of 4Hz to 30,000Hz(-3dB).
Applications:Primarily used for vibration monitoring in aero-derivative gas turbines,the monitor can be connected to Velomitor sensors and accelerometers to enable real-time monitoring and data analysis of gas turbine vibration conditions,ensuring safe and reliable operation.
