1771-INGA50

The 1771-INGA50 is a manufactured by Allen-Bradley and it is a discrete I/O backplane interface module for the 1771 series. The 1771-INGA50 supports 16 inputs and operates on a voltage of 24 Volts DC/AC. The operating AC voltage range for the device is 16 to 30 Volts AC and the DC operating voltage range is 9 to 30 Volts DC. The 1771-INGA50 has a backplane current of 250 mA. The module is mounted using rack mounting. The typical AC ON-signal delay for the 1771-INGA50 is 35 milliseconds and the typical DC ON-signal delay is 45 milliseconds. However, the AC OFF-signal delay is 45 milliseconds and the typical OFF-signal delay is 50 milliseconds.

The 1771-INGA50 is to be operated in an industrial environment which has a pollution degree 2 rating. Also, the module can handle Category 2 levels of over-voltage. While installing the module, make sure to follow the guidelines which are mentioned in the installation or the service manual to prevent any malfunctioning of the equipment. Also, it is necessary to install the device while observing and maintaining the minimum clearances to maintain the temperature of the device in the enclosure and to ensure the optimum performance and long life of the device. It is necessary to maintain the ambient temperature of the device within the range as specified by the manufacturer. Operators can use cooling fans or heaters if required to get the temperature within the proper range. Make sure to prevent electrostatic discharge because the device might be sensitive to ESD and this can damage the equipment.
