DescriptionThe DPF9300 digital input panel meter offers many features and performance capabilities to suit a wide range of industrial applications. The DPF9300 offers both counting and rate in the same package. The optional plug-in output cards allow the opportunity to configure the meter for present applications, while providing easy upgrades for future needs. The meters employ a bright 14 mm (0.56") LED display. The intensity of the red LED display can be adjusted from dark room applications up to sunlight readable, making it ideal for viewing in bright light or dark room applications. The meters accept digital inputs from a variety of sources including switch contacts, outputs from CMOS or TTL circuits, magnetic pickups and all standard RLC sensors. The meter can accept directional, unidirectional or quadrature signals simultaneously. The maximum input signal varies up to 34 KHz depending on the count mode and function configurations programmed. Each input signal can be independently scaled to various process values. The rate meters provide a MAX and MIN reading memory with programmable capture time. The capture time is used to prevent detection of false max or min readings which may occur during start-up or unusual process events. The meters have four set point outputs, implemented on plug-in option cards. The plug-in cards provide dual FORM-C relays (5A), quad FORM-A (3A), or either quad sinking or quad sourcing open collector logic outputs. The setpoint alarms can be configured to suit a variety of control and alarm requirements. Communication and Bus capabilities are also available as option card through the bus. Additionally, the meters have a feature that allows a remote computer to directly control the outputs of the meter.
With an RS232 or RS485 card installed, it is possible to configure the meter using free software. The configuration data can be saved to a file for later recall. A linear DC output signal is available as a plug in option card. The card provides either 20 mA or 10V signals. The output can be scaled independent of the input range and can track any of the counter or rate displays.
Once the meters have been initially configured, the parameter list may be locked out from further modification in its entirety or only the set point values can be made accessible. The meters have been specifically designed for harsh industrial environments. With NEMA 4X (IP65) sealed bezel and extensive testing of noise effects to CE requirements, the meter provides a tough yet reliable application solution.
