Information About 1785-L40C

The Allen-Bradley 1785-L40C PLC-5/40C is a controller with ControlNet network capability, featuring a 48-KB word SRAM processor. This module is installed in the I/O slot of the 1771 I/O chassis and is used to control field device inputs and outputs. It offers a maximum user memory of 48KB words and an I/O capacity of 2048 (2048 inputs and 2048 outputs complementary). The module has a maximum program scan time of 0.5ms per K-word for bit logic and a typical scan time of 2ms per K-word. It draws 3.3A from the backplane at 5V DC and dissipates a maximum of 59 BTU/hour.

The 1785-L40C supports the 1785-CHBM ControlNet Hot Backup Cartridge and is compatible with 1771, 1794, 1746, and 1791 I/O modules, including 8-point, 16-point, 32-point, and intelligent I/O modules. It features an RJ45 ControlNet Network Access Port with an I/O transmission rate of 5Mbps and a user-selectable network update time between 2-100ms, along with a co-processor port.

Additional interfaces include an 8-pin mini-DIN programming connector, a 3-pin DH+ port, and a 25-pin D-shell serial port with transmission rates from 57.6Kbps to 230.4Kbps and a scan port time from 10ms per rack at 57.6Kbps to 3ms per rack at 230Kbps. The controller operates at temperatures between 0-60°C (32-140°F) with 5-95% non-condensing relative humidity and can be stored at -40-85°C (-40-185°F). It withstands 30G operational shock, 1G vibration at 10-500Hz, and has an open-style enclosure. Weighing 1.42kg (3lbs), the 1785-L40C is UL, CE, CSA, and C-TICK certified.
