1775L2C

The 1775L2C model from Allen Bradley is a key component in the PLC 3 series, acting as the main processor module. This Level 2 controller utilizes four AMD 2903 bit-slice CPUs, providing significant processing power for various applications. Positioning within the two leftmost slots of the chassis ensures proper connectivity and accessibility.

This processor module notably draws 94A at +5V DC and 40mA at +15V DC, indicating its power requirements for robust functionality. With a capability to execute over 70 different instructions, the 1775L2C offers a flexible and expandable data table type, allowing users to adapt the system as necessary.

The programming execution is controlled through MCR, JMP, and JSR functions, which enhance the module's operational flexibility. Additionally, it includes real-time interrupt capabilities that enable immediate processing of time-sensitive tasks. The supported numeric formats include both floating point and high-order integers, catering to various data processing requirements.

Fault management is integrated into the module by allowing programmable fault responses, which aids in maintaining system reliability. Furthermore, this processor supports scheduling functions through a real-time clock and calendar, making it suitable for applications needing precise timing and control.
