Description
Product Description
The MEIYO SPR-P06-I is a marine and industrial speed relay designed for rotational-speed monitoring and signal transmission. Available documentation identifies the unit as a speed relay with a 24 VDC power supply and a 4–20 mA DC output signal. The unit is associated with MEIYO Electric marine and industrial automation equipment and can be used for speed monitoring in engine and machinery-control applications. The documented identification includes E575 and 46111-045300.
The SPR-P06-I is intended to provide a standardized analog speed signal for integration with monitoring, alarm, indication, or control equipment. The manufacturer’s current website still lists the SPR-P06 product family under its speed-related equipment, while the exact SPR-P06-I configuration should be matched to the vessel or machinery system before replacement.
