Expert Technical Evaluation & Performance Review
Processing Power and Memory Architecture
The 1785-L86B standard processor uses a powerful 100 Kilowords memory. This battery-backed static RAM retains your programs. It also supports EEPROM backup via optional modules. This design ensures your critical logic stays safe.
High-Speed I/O and Communication
This module scans a remote rack in just 3 ms. It achieves this speed at 230.4 kbits/s for fast data flow. The controller communicates through four Data Highway Plus ports. It also includes one RS-232-C/422-A/423-A port for configuration. You can easily integrate this unit into existing networks.
System Capacity and Expansion
You can connect up to 93 I/O chassis with this controller. It supports 32 remote chassis on each link for wide coverage. The processor handles a maximum of 24 I/O racks. This capacity lets you manage large-scale systems from a single slot.
Robust Electrical and Environmental Design
This processor draws only 3.3A from the 5V backplane. It provides voltage isolation tested to 500V for 60 seconds. The unit operates reliably from 0 to 60 degrees Celsius. It also withstands 30G of operational shock. This rugged design ensures long service life in harsh conditions.
Product Procurement & Buyer Guide
Matching Your Application Needs
