DescriptionThe 1900/65A General Purpose Equipment Monitor is made to constantly check and protect equipment used in many different fields and industries. Its low price makes it a great choice for general machines and processes that need ongoing monitoring and protection.
The user defines monitor operation and the Modbus Gateway register map by using software running on a laptop or PC to create a configuration file and download the file to the monitor through the built-in Ethernet connection. The 1900/65A permanently stores configuration information in non-volatile memory and can upload this information to the PC for changes.
The 1900/65A provides four transducer inputs and four temperature inputs. Software can configure each transducer input to support 2- and 3-wire accelerometers, velocity sensors, or proximity sensors. Each temperature input supports Type E, J, K, and T thermocouples, and 2- or 3-wire RTDs.
Outputs
The 1900/65A provides six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered output. The user can use the 1900 Configuration software to configure the relay contacts to open or close according to the OK, Alert, and Danger statuses of any channel or combination of channels, and to provide data from any variable from any channel on any recorder output. The dedicated buffer output can provide the signal for each transducer input.
A Modbus Gateway option allows the monitor to provide static variables, statuses, event list, time and date information directly to any Modbus client, including Distributed Control Systems (DCSs), Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), or System 1 software. The monitor uses an internal counter and a Modbus client/master time reference to generate time and date information. Users can upgrade monitors without the Modbus Gateway by ordering the 1900/01 Communications Upgrade (see the Ordering Information section). The 1900/65A supports Modbus communications via Ethernet and a software-configurable RS232/485 serial port.
Configuration
The user defines monitor operation and the Modbus Gateway register map by using software running on a laptop or PC to create a configuration file and download the file to the monitor through the built-in Ethernet connection. The 1900/65A permanently stores configuration information in non-volatile memory and can upload this information to the PC for changes.
Display Module
The 1900/65A supports an optional display/keypad to view channel information or make minor configuration changes. This allows the 1900/65A to operate as a stand-alone package. If desired, the user can mount the display up to 75 metres (250 feet) from the Monitor Module.

Inputs
Transducer Inputs
Users can configure Channels 1 through 4 to accept input from acceleration, velocity, or displacement transducers.
Transducer Channel Types
Channel Types define the functionality for processing that will be applied to an input signal and the kind of variables or measurement values that will be derived from this input. Channel Types also define the kind of sensor that must be used. Transducer Channel Types include:
Channel Types define the functionality for processing that will be applied to an input signal and the kind of variables or measurement values that will be derived from this input. Channel Types also define the kind of sensor that must be used.
Transducer Channel Types include:
Acceleration and Reciprocating Acceleration Channel Types
The Acceleration Channel Type and Reciprocating Acceleration Channel Type support two- and three-wire acceleration sensors. The Reciprocating Acceleration channel type has timed OK channel defeat disabled.
Acceleration Variables and Reciprocating Acceleration Variables
Acceleration Variables and Reciprocating Acceleration Variables are filtered and processed measurements from raw transducer signals. The Acceleration Channel Type and Reciprocating Acceleration Channel Type continuously process up to four variables per channel.
Vibration: Up to three bandpass-filtered amplitude measurements.
Acceleration Enveloping: Users can apply the acceleration enveloping algorithm to one Acceleration or Reciprocating Acceleration Variable.
Bias Voltage: Users may assign the value of the transducer bias voltage to any of the variables.
Configuration Options: Each variable is independently configured with the following options.
Filters
Vibration Variable 0.5 Hz – 25 kHz configurable 4-pole high-pass, 4-pole low pass
Enveloping High-Pass 25 Hz to 5 kHz, configurable 4-pole
Enveloping Low-Pass 125 Hz to 25 kHz, configurable 2-pole
Enveloped Variable High-Pass 0.1 Hz min., but greater than Enveloped Variable Low-Pass 2-pole
Enveloped Variable Low-Pass Greater than Enveloped Variable high-pass and less than Enveloping high-pass 4-pole
Bias Filter 0.01 Hz 1-pole low-pass
OK Filter 2.4 kHz 1-pole low-pass
Velocity and Reciprocating Velocity Channel Type
The Velocity Channel Type and Reciprocating Velocity Channel Type support two-wire and three-wire piezo velocity sensors.
Velocity Variables and Reciprocating Velocity Variables
Velocity Variables and Reciprocating Velocity Variables are filtered and processed measurements from raw transducer signals. The Velocity Channel Type and Reciprocating Velocity Channel Type support up to four continuously calculated variables per channel.
Configurable Options
Each variable is independently configured with the following options.
