1745-LP157

The Allen Bradley 1745-LP157 is part of the SLC 150 series and functions as a processor unit. It operates on a supply voltage that falls between 18 to 30 Volts DC, allowing it to be applied in a variety of control systems. This model provides 20 distinct input channels alongside 12 output channels, accommodating a flexible range of control requirements.

The specified input/output voltage range is between 10 and 50 Volts DC, with relay outputs capable of managing both 10 to 250 Volts DC and AC. This adaptability enables it to interact seamlessly with multiple devices in a control environment.

Performance-wise, the unit boasts a typical scan time of just 15 milliseconds which supports efficient processing. Reliability is heightened by a non-rechargeable lithium battery that has a lifespan of approximately 2 to 3 years, allowing for sustained operation. The backup battery offers a capacity of 1,350 milliampere-hours, ensuring it can provide power for essential tasks. For wiring applications, the unit is compatible with 14 AWG wire sizes. Status indicators consist of five red LEDs which aid in monitoring operational conditions. The memory type is based on electrically erasable programmable read-only memory (EEPROM), facilitating firmware updates and data retention under various conditions. Lastly, this unit operates within a rated frequency of 50 to 60 Hertz, allowing it to align with standard power supply specifications.
