The Allen Bradley 813S-V1-500V-230 is a voltage monitoring relay designed for single-phase applications. It provides reliable under- and overvoltage protection across a wide voltage range from 2 V to 500 V AC or DC. This device operates on a control power supply of 115 or 230 V AC and features a single-pole double-throw (SPDT) contact. It also includes an adjustable time delay, allowing you to fine-tune response times based on your system’s needs. Additionally, the relay offers programmable functions such as latch or inhibit at the set voltage level, with an automatic reset capability. Distributed by BSP Automation, this voltage monitor is a solid choice for safeguarding equipment against voltage fluctuations in industrial settings.
