Technical Specifications

Version & Model Difference

The SR469P5HIA20 is a specific configuration within the 469 series. The part number breaks down as follows: 'SR469' indicates the base relay, 'P' denotes a 5A CT secondary, '5' refers to the control power option (120V AC), 'H' indicates the high-performance version with enhanced memory and processing, 'I' signifies the RS485 communication port, and 'A20' is a hardware revision code. Compared to other versions, this model does not include an optional analog output module or additional communication protocols like Profibus or DeviceNet. The 'H' version offers more event recording capacity and faster processing than the standard version.
