Models 5000 & 5005 (CPU Card) Multi-Channel Signal Conditioners

The Model 5000 & 5005 Signal Conditioners allow several different types of vibration sensor and process information to be converted to standard outputs that can then be processed by instrumentation that requires 4-20mA inputs (or RS232/485 on the Model 5005). Two-Color LED's provide visual Input Fault status. A fail-safe SPDT relay provides a fault indication when there is a loss of power, or when there is a fault detected on any channel. Dynamic signal outputs are provided on BNC connectors for each channel allowing personnel to collect the data from one location.

Model 5000

The Model 5000 converts input transducer signals to 4 to 20 mA outputs for transmission to a PLC or computer where alarm and trip are accomplished.

PMC transmitters interface with transducers for measuring:

- Vibration
- Thrust Position
- Temperature
- RPM
- Phase
- Pressure
- Flow

And other parameter for monitoring and protection.

PMC multi-channel transmitters convert input signals to either 4 to 20 mA outputs or serial RS232/485 outputs proportional to the input signals for transmission to a PLC or a computer…for trending, alarm and shutdown.

Unattended continuous monitoring provides the greatest assurance of reduced maintenance, repair and unplanned downtime costs.

The Model 5000 dual channel signal conditioners perform three primary functions:

Provide and isolated 4 to 20 mA output signal proportional to vibration, RPM, temperature, etc.

Provide a local buffered AC vibration output on a BNC connector for machinery diagnostics, isolated from the 4 to 20 mA output.

Provide a sensor fault circuit and relay.

The sensor fault circuit detects an open or short in the transducer or wiring and, in the case of a fault, causes the common fault relay located in the power supply to actuate. An LED on the signal conditioner illuminates, indicating that the channel is in a fault condition.

The signal conditioners can be removed or inserted without powering down. This permits a defective signal conditioner to be removed or replaced without disturbing the other channels.

A typical monitoring system will consist of a rack with back plane, plug-in power supply, and the appropriate number of dual channel signal conditioners for vibration, position, RPM, temperature, etc.

Three rack sizes are available, depending on the number of points to be monitored.

5000R8, up to 8 channels (6 on Model 5005)

5000R12, up to 16 channels (14 on Model 5005)

5000R21, up to 34 channels (32 on Model 5005)

Normally PMC/BETA supplies the vibration, position and RPM transducers. However, for upgrading existing monitoring systems on turbines, pumps, compressors, etc., the 5000 Series can be supplied to interface with existing probes and transducers of other manufacturers.

Since temperature RTDs are usually mounted inside the machine bearings or motor windings, these devices are most often supplied by the machinery manufacturer or customer.

Model 5005

The Model 5005 converts transducer inputs directly to a serial RS232 or 485 output for transmission to a host computer over a single set of wires. Alarm and trip are accomplished at the computer.

For those plants where the existing data communication system is not a 4 to 20 mA based system, the Model 5005 offers dramatic cost savings by permitting serial digital transmission of all data channels on one set of wires. Further, many analog inputs at the computer are replaced with one serial port.

The Model 5005 includes a rack which holds the power supply, CPU card, and up to 16 dual channel signal conditioners. It is identical to the Model 5000 except for the addition of the plug-in CPU card with communication software. As shown, the CPU card is located adjacent to the power supply. The serial RS232, 422 or 485 output is available on a DB25 connector. RS485 permits multi-drop operation with other instruments.

The Model 5005 will interface to new or existing displacement proximity probes, accelerometers, velocity vibration transducers, RTDs or tachometer probes.

In addition, a 4 to 20 mA output from any pressure, level or flow transmitter, etc. can be accepted by the Model 5005 and digitized for serial transmission.

Model 5005

The Model 5005 performs three primary functions:

Provides an RS232, 422 or 485 serial output.

Provides a local buffered AC vibration output on a BNC connector.

Provides a sensor fault circuit and relay.
