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. Application Scenarios Can the SR469P5HIA20 be retrofitted into an existing motor control center? Yes, the 469 relay is designed for panel mounting and can be retrofitted into most motor control centers. It requires standard CTs with 5A secondary and a control power source of 120V AC. The relay's compact size and flexible mounting options make it suitable for retrofit applications. Ensure that the CTs are properly rated and that the control power is within the specified range. What communication protocols are supported by this relay? The SR469P5HIA20 comes standard with RS485 communication using Modbus RTU protocol. Optional modules can be added to support Profibus DP, DeviceNet, or Ethernet (Modbus TCP/IP). These modules are field-installable and allow integration with various industrial networks. How many RTDs can be connected to the SR469P5HIA20? The relay supports up to 24 RTD inputs (3-wire) for stator and bearing temperature monitoring. The RTDs can be 100Ω platinum or 120Ω nickel types. This allows comprehensive thermal protection and monitoring of motor health. What is the difference between the SR469P5HIA20 and other 469 models? The SR469P5HIA20 is a specific configuration with 5A CT secondary, 120V AC control power, and RS485 Modbus communication. Other models may have different CT ratings (1A or 5A), control power options (24V DC, 48V DC, 120V AC, 240V AC), or additional communication modules (Profibus, DeviceNet, Ethernet). The 'H' in the part number indicates a high-performance version with enhanced memory and processing capabilities.
