Processing Performance
The Honeywell 620-1631 uses a 32-bit RISC processor for fast program execution. This CPU executes boolean instructions in just 0.2 microseconds. Therefore, the module handles complex automation tasks with ease. The 4 MB of RAM stores user programs and real-time data. Hence, you can implement large control strategies without memory limitations.
Memory and Storage
This processor module includes 8 MB of flash memory for permanent program storage. Consequently, you do not need external memory cards for application backup. The flash memory retains all data even when you remove power completely. Thus, the Honeywell 620-1631 boots up quickly after power restoration. The module also stores historical logs and event records in flash.
Communication Interfaces
The Honeywell 620-1631 offers one RS-232/485 serial port for programming. It also provides one Ethernet port with 10/100 Mbps auto-negotiation. Therefore, you can connect this module to plant-wide control networks. The expansion interface links to additional I/O modules and peripherals. Consequently, the system scales easily as your application grows.
Backup and Energy Storage
The lithium battery retains RAM contents for up to five years. Hence, your program stays safe even when power fails completely. The 470µF capacitor provides 30 seconds of backup during battery replacement. Thus, you can change the battery without losing any data. The Honeywell 620-1631 includes a battery low indicator on its front panel.
Installation and Connectivity
You can mount the Honeywell 620-1631 on a standard DIN rail. Alternatively, secure it with M4 screws through its four mounting holes. The Ethernet port accepts standard RJ45 patch cables. The serial port uses a 9-pin D-sub connector for easy wiring. The Honeywell 620-1631 works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This processor module operates reliably from 0°C to +55°C. It also withstands 90% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the Honeywell 620-1631 suits most industrial control cabinets perfectly.
