Operating within the PLC 5 family, the Allen Bradley 1785-V40L processor module is engineered to facilitate advanced control in automation setups. This module supports a maximum of 48,000 words in user memory, providing the necessary space for substantial programming tasks. The program scan times are efficient, measuring 0.5 milliseconds per 1,000 words for bit logic operations and 2 milliseconds per 1,000 words under typical conditions.

Equipped with an RS-232 serial port for communication, the 1785-V40L also encompasses the capability to connect with 15 I/O racks, thereby enhancing system expandability and allowing for a total I/O capacity of 1920 across any mixture of inputs and outputs. The module can efficiently accommodate up to 1920 inputs and outputs in complementary arrangements as well as support for up to 1920 analog I/O channels. RIO transmission rates are notably flexible, functioning at 57.6 kbps, 115.2 kbps, or 230 kbps.

Additionally, the module features two ports for DH+ or remote I/O communication, facilitating optimal data exchange across networks. The capacity for additional installations is considerable, permitting a maximum of 16 extended local I/O chassis and an impressive 60 remote I/O chassis. The overall weight of the unit is approximately 1.5 pounds. For electrical sourcing, the backplane current load is rated at 2.9 Amperes typically, with a maximum load of 3.5 Amperes, ensuring robust operation under varied conditions.
