Functional Description

5461-650 is a T/C Input Board developed by Woodward. Thermocouples are widely used in various industries to measure temperature accurately and reliably. They consist of two different metal wires joined together at one end, which generate a voltage proportional to the temperature difference between the joined end and the measuring point. It acts as an interface between the thermocouples and the control system, allowing for precise temperature monitoring and control. This product has been discontinued by the Manufacture from production. Contact WOC for the availability of this module.

Features

• Connect a single-pole, single-throw contact from terminal 16 (low voltage controls: terminal 0) to terminal 19, the Close For Rated (open for idle, close for rated) terminal. Oil pressure is frequently used to seal this contact. When terminal 19 is closed, 20 to 40 Vdc is applied, and the prime mover can operate at a speed greater than idle. When the contact is opened, the voltage is removed from terminal 19, and the speed of the prime mover is immediately reduced to idle.
• Terminals 20 (+) and 21 are connected by the actuator wires (-). Use shielded wires and connect the shield to terminal 22. Connecting the shield to the actuator or any other point is not permitted.
• The shield must be continuous all the way to the actuator and isolated from all other conducting surfaces.
• If a remote Speed Trim potentiometer is used, a jumper must be connected to terminals 23 and 24. If you use a Speed Trim potentiometer. Connect it using shielded wire. Connect terminal 22 to the shield. Check that the shield has continuity all the way to the potentiometer and that it is isolated from all other conducting surfaces. A 100 potentiometer will allow you to adjust the speed by 5%. Smaller potentiometers can be used if less adjustment is required. Potentiometers with multiple turns are recommended.

• Input deviation alarms are used to notify you if any of the input channels or input legs detect a value that differs from the application's voted-good value. An input channel alarm will be issued if the sensed value of an input channel deviates from the voted-good value by a greater margin than its "Max Deviation" setting. An annunciation of this type can be used to indicate when an input channel or system transducer is out of calibration. Typically, the Max Deviation setting is set to 1% of the configured input range. In the event of a deviation alarm condition, the alarmed input is not removed from the control's voting logic and can still be used to control with if all other channels fail.

Product Attributes

• For external signals and power, the NPM module has three card edge connectors (P1, P2 and P3). Connector P1 connects to the Controlway, common (ground), and +5 VDC power. ConnectorP2 connects the NPM and NIS modules.
• Connecto rP3 communicates between the primary and backup process control unit interfaces. The NPM module communicates with the NIS module via the I/O expander bus within its process control unit.

Troubleshooting

• The Module features the capability to receive information from thermocouples, which can be of either J or K type. The specific type of thermocouple used is determined and selected within the application program. Additionally, the module is equipped with an AD592 ambient temperature sensor that is mounted directly on the module. This sensor serves the purpose of cold junction temperature sensing, enabling compensation for temperature variations at the cold junction.
• The compensation for the cold junction temperature is performed in software, utilizing the readings from the AD592 sensor. By accounting for the ambient temperature at the cold junction, accurate temperature measurements can be achieved for the thermocouple inputs.
• The module offers two versions: fail high and fail low. The version is selected by adjusting the jumpers on the module board. These jumpers enable the input channels to be pulled either high or low in case of an open input. This feature ensures that a specific signal is maintained when an input is not connected, preventing erratic or inaccurate readings.
• Each input channel on the module is multiplexed to a voltage-to-frequency converter. This converter converts the incoming analog voltage from the thermocouple or ambient temperature sensor into a frequency signal. The module processor reads the period of this frequency signal and converts it into a count. This count is then transmitted via the transceiver module to the LINKnet controller module, which handles data communication within the network.
