Products Description

The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module used to provide Keyphasor signals to the monitor modules in a 3500 rack. The module receives input signals from proximity probes or magnetic pickups and converts the signals to digital Keyphasor signals that indicate when the Keyphasor mark on the shaft coincides with the Keyphasor transducer. The 3500 Machinery Protection System can accept up to four Keyphasor signals for normal configuration and up to eight Keyphasor signals in a paired configuration.

The Enhanced Keyphasor Module is an improved 3500 system module. It offers expanded Keyphasor signal processing capabilities over the previous design while maintaining complete downward-compatibility in terms of form, fit and function with existing Keyphasor modules for use in legacy systems. The Keyphasor module, PWA 125792-01, is completely replaced by the more recent 149369-01 module.
When a system Keyphasor input is required for Triple Modular Redundant (TMR) applications, the 3500 system should employ two Keyphasor modules. In this configuration the modules work in parallel to provide both a primary and secondary Keyphasor signal to the other modules in the rack.
A system with more than four Keyphasor inputs may use a paired configuration provided that there are no more than four primary Keyphasor input signals. A paired configuration requires two consecutive monitoring positions in either the upper/lower or both half-slot positions. Four Keyphasor modules will accept four primary and four backup input channels and provide four output channels (one per module). A configuration of two paired and one non-paired (three Keyphasor modules total) is also possible. In such a configuration, the user may configure the one non-paired Keyphasor (order either two 2-channel or one 1-channel and
one 2-channel option)
The Isolated Keyphasor I/O module is designed for applications in which the Keyphasor signals are tied in parallel to multiple devices and require isolation from other systems, such as a control system. The Isolated I/O module was created specifically for Magnetic Pickup applications but is compatible with and will provide isolation for Proximitor* applications as long as an external power supply is provided. Note that the intent of this I/O module was primarily to measure shaft speed and not phase. The module can provide phase measurements, but this I/O introduces a slightly higher phase shift than the NonIsolated I/O version. Figure 1 shows the amount of phase shift that the Isolated I/O modules will add at different machine speeds.
Enhanced product features include generation of once-per-turn event signals from multi-event-per-turn inputs, field-upgradeable firmware, and asset management data reporting.

Analog signal, there are two, voltage or current signal, is generally the signal transmitted by the transmitter, such as the pressure transmitter to detect the water pipe pressure, it will output an analog signal 4- 20ma or 0-10V signal to PLC, PLC for data processing.

Switching quantity input point (DI), processing switching quantity input signal.

Analog input point (AI), processing analog input signal (0-20 MADc,0-5VDC).

Resistance signal (including thermal resistance) input point, processing thermal resistance or general resistance signal.

High speed pulse input point, processing high speed pulse signal.

Voltage (including thermocouple) input point, processing voltage input or thermocouple signal.

There is also communication, used to exchange data with the upper computer or control the subordinate controller instrument driver

1.2 Difference between digital and analog input modules
According to the difference of field input signal, input module can be divided into switching input module and analog input module.

The function of switching input module is to convert various switching signals into TTL standard signals required by CPU. According to the input power supply type, it can also be DC input module and AC input module. The input signal is converted into TTL (5V) standard signal by photoelectric coupling after voltage division, current limiting and filtering.
