SR469-P5-HI-A20 motor management relay 88-300VDC

The provided text describes the specifications and connections for analog inputs and outputs on a device, likely a control or monitoring system. Here's a breakdown of the key points:

Analog Inputs (AI):

The device provides terminals for four 0 to 1mA, 0 to 20mA, or 4 to 20mA current input signals, which are field programmable.

These inputs are used to monitor external quantities such as vibration, pressure, or flow.

All four inputs share one common return, and proper polarity observation is necessary for correct operation.

The analog input circuitry is isolated as a group with the analog output circuitry and the RTD circuitry.

Transorbs limit isolation to ±36 V with respect to the device's safety ground.

The +24 V DC analog input supply is provided for control power of loop-powered transducers, with maximum current draw specified in the specifications section.

Analog Outputs (AO):

The device provides four analog output channels, configurable for a full-scale range of either 0 to 1 mA or 4 to 20 mA.

Each channel can be configured to provide full-scale output sensitivity for any range of any measured parameter.

Similar to analog inputs, analog outputs share one common return, and proper polarity observation is crucial.

Shielded cable usage with one end of the shield grounded is recommended to minimize noise effects.

Analog output circuitry is isolated with the analog input and RTD circuitry, and Transorbs limit isolation to ±36 V with respect to the device's safety ground.

If a voltage output is needed, a burden resistor must be connected at the input of the SCADA measuring device, with the resistor value calculated based on the full-scale voltage and maximum current.

Overall, the text provides detailed information on the configuration, connections, and precautions for analog inputs and outputs, ensuring proper operation and minimizing noise interference.
