Allen-Bradley 1756-PSCA2 Chassis Adapter Module

The main output voltage is 5V DC, which is the standard working voltage for most modules in the ControlLogix series. The output current can reach 20A (specific parameters are subject to the product manual), which can provide sufficient power for a large number of modules on the rack.

Some models may provide 24V DC auxiliary output for powering small sensors, actuators and other devices. The output current is generally 2A (specific parameters are subject to the product manual), meeting the power supply needs of low-power devices.
Power output: The rated output power is usually 100W (specific parameters are subject to the product manual), which can meet the power supply requirements of medium and large ControlLogix control systems and ensure stable operation of the system under full load conditions.
Efficiency: It has a high conversion efficiency, usually above 85% (specific efficiency value is subject to the product manual). It can effectively reduce energy loss, lower operating costs, reduce heat generation of the module itself, and extend the service life.
Protection functions:

Overcurrent protection: When the output current exceeds the rated value, the module will automatically limit the output current or cut off the output to prevent damage to the power module and connected equipment due to overload.

Overvoltage protection: If the output voltage rises abnormally and exceeds the set threshold, the module will activate the protection mechanism to avoid damage to downstream modules caused by high voltage.

Short-circuit protection: When a short-circuit fault occurs at the output end, the module can respond quickly and cut off the output. It can resume normal operation after the short-circuit fault is eliminated, ensuring system safety.

Over-temperature protection: When the internal temperature of the module exceeds the specified limit, it will automatically reduce the output power or stop output to prevent the module from being damaged due to overheating.

Undervoltage protection: When the input voltage is too low, the module will trigger protection to avoid abnormal operation of equipment caused by insufficient voltage.
Environmental adaptability:

Operating temperature: It can work stably within the temperature range of 0°C - 60°C, adapting to common temperature changes in industrial sites.

Relative humidity: It can operate normally in a relative humidity environment of 5% - 95% (non-condensing), suitable for humid production workshops and other environments.

Vibration and shock resistance: It complies with relevant industrial standards such as IEC 61131-2, has certain vibration and shock resistance capabilities, and can work reliably in industrial occasions with slight vibrations (such as near production lines and heavy machinery).
