Description

The Allen-Bradley 1785-L60B serves as a high-capacity central processing unit within the PLC-5 family. This processor offers 64,000 words of battery-backed static RAM for extensive program storage. It handles complex control tasks for medium to large industrial applications effectively. Furthermore, the module supports up to 3072 total I/O points across multiple chassis. Users can configure the system for standard or complementary I/O addressing modes. This flexibility allows the 1785-L60B to manage up to 93 individual I/O chassis. Consequently, it remains a powerful solution for integrated factory-wide automation.

Versatile Communication and Interface Options

This PLC-5/60 module features several dedicated ports to ensure seamless network connectivity. It includes four specialized ports for DH+ or Remote I/O link configurations. Additionally, an onboard 25-pin Sub-D serial port supports RS-232, RS-423, and RS-422A communication. The processor utilizes DF1 protocols to exchange data with peripheral devices efficiently. Two extra programming terminal ports allow for local system configuration and monitoring. Front-panel status LEDs provide immediate feedback on battery life, processor mode, and force conditions. These indicators help technicians maintain high system availability.

Memory Safeguards and System Reliability

The 1785-L60B integrates several features to protect critical application data. Users can install optional EEPROM modules like the 1785-ME64 for non-volatile backup. These modules prevent program loss during extended power outages or battery failures. Moreover, the processor fits into any standard 1771 I/O chassis for easy installation. The hardware operates reliably in temperatures ranging from 0°C to 60°C. It also resists physical stress with a 30g shock rating and 2g vibration resistance. This rugged design ensures consistent performance in demanding manufacturing environments.
