Technical Specifications

Information About 1785-L30B

The Allen-Bradley 1785-L30B is a member of the PLC5 Controller series designed and manufactured by Rockwell Automation. This standard programmable logic controller (PLC) is equipped with 32K words of user memory, providing a robust platform for industrial control applications.

The controller supports a versatile I/O configuration, accommodating up to 1024 I/O points in any mix, or a combination of 1024 input and 1024 output points in a complementary setup. This flexibility allows for tailored configurations to meet the specific needs of diverse automation setups.

Embedded communication interfaces play a crucial role in facilitating seamless connectivity and data exchange within the control system. The 1785-L30B features Two (2) DH+/Remote I/O ports, supporting both adapter and scanner functionality. Additionally, it incorporates One (1) serial port that is configurable for RS-232, RS-423, and RS-422A standards, further enhancing its communication capabilities.

For efficient operation and data integrity, the controller utilizes battery-backed static RAM (SRAM), ensuring that critical information is retained even in the event of a power interruption. The 1770-XYC battery is employed for this purpose, providing reliable backup power to the SRAM.

The PLC5 series, to which the 1785-L30B belongs, is known for its robust and reliable performance in industrial automation. This particular model is categorized as a standard processor within the series, offering a balance of features suitable for a wide range of control applications.

The controller's environmental specifications adhere to industry standards, with an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). For non-operating conditions, it can withstand temperatures ranging from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit).

The backplane current load is specified at 2.3 A, contributing to efficient power distribution within the control system. The controller is compatible with various power supply options, including 1771-P4S, -P6S, -P4S1, and -P6S1 models.
