Product Description
The Allen-Bradley 1785-L86B PLC-5/86 is a high-speed programmable controller with protected memory designed for single-slot installation in a 1771 I/O chassis. It manages up to 3072 I/O points across a maximum of 24 I/O racks, supporting 93 I/O chassis links with 32 remote chassis per link, and utilizes 100K words of SRAM. It requires 3.3A at 5V DC backplane current, dissipates 17.3W of heat, and withstands 30G shock and 2G vibration (10-500Hz). Featuring 500V isolation between communication ports and 300V between ports and the 1785-RC relay cartridge, it's compatible with 1771 memory modules and supports various I/O modules (8, 16, 32-point, and intelligent) with multiple addressing modes. Communication is facilitated through 4 Data Highway Plus/Remote I/O ports, supporting Ladder Logic, Sequential, and Structured Text programming. Operating temperature ranges from 0 to 60C (32 to 140F) at 5-95% RH (non-condensing), with a storage range of -40 to 85C (-40 to 185F). The unit weighs 1.42kg and complies with CSA, UL, C-TICK, and CE standards.
Is Your Device Showing These Signs?
The Allen Bradley 1785-L86B PLC processor commonly experiences issues such as memory corruption leading to program faults, backplane communication failures causing I/O module errors, and power supply degradation resulting in intermittent shutdowns. Firmware corruption necessitates reprogramming, while battery depletion leads to memory loss requiring a reload of the application program. Resolving these problems involves memory diagnostics, backplane testing, power supply replacement, firmware upgrades, and battery replacement to restore the processor to optimal operational status.
