Littelfuse, Inc. Industrial Relays 201-200-SP-DPDT

The 201-200-SP-DPDT is a voltage monitoring relay designed for single-phase motors operating within a voltage range of 190-240VAC and a frequency of 50/60Hz. It features two isolated Form C relay outputs, allowing for control of two separate circuits with different voltage requirements. The device employs a microcontroller-based circuit that continuously monitors voltage levels to detect harmful conditions, activating the relays only after a specified trip delay of 4 seconds to prevent nuisance tripping from transient voltage fluctuations. Once normal conditions are restored, the relays will reactivate after a restart delay of 2 seconds. The relay operates within an ambient temperature range of -20° to 70°C and has a maximum input power of 5W. It is rated for pilot duty at 480VA and general-purpose applications at 10A @ 240VAC. The product complies with various safety and immunity standards, including UL508 and CE certifications. It is designed for easy installation using an 8-pin octal socket (Model OT08PC), which can be mounted on a DIN rail or surface. The compact dimensions of the relay are 44.45 mm in height, 60.325 mm in width, and 104.775 mm in depth, with a weight of 0.65 lb.
