RPR-1PS Pulse Isolation Relay

RPR-1PS Pulse Isolation Relay

B Series

The RPR-1PS pulse isolation relay is designed to provide a single isolated solid state Form C (K, Y, & Z) contact from a single Form C input. The RPR-1PS supplies its own sense voltage to the pulse sending unit, usually an electric meter’s pulse initiator.

Typical applications include interfaces between utility metering devices and customer-owned energy control systems, demand recorder applications, and supervisory control systems (SCADA) interfaces.

The RPR-1PS relay is designed to filter noise and transients from its input to prevent any false pulses at its output. Bright red and green LED indicators display the system’s status at all times, thus allowing a rapid visual check of the system’s performance without requiring any additional test equipment.

The RPR-1PS’ input and output circuit’s terminal strip is a “Euro” type connector. The “K” lead of the RPR-1PS’ output is fused to prevent damage to the relay under almost any condition a user might cause such as excessive current, incorrect wiring, etc. The RPR-1PS’ robust solid state switching device is rated at 800V and 750mA giving maximum protection from lightning or transient voltage damage. Its built-in transient protection for the solid state switch contacts eliminates the need for external or off-board transient suppression devices. All component parts that have power applied to them, with the exception of the input/output terminal strip, are enclosed in a polycarbonate cover for maximum protection. The mounting base plate is also made of polycarbonate and offers excellent electrical insulation between the circuit and the mounting surface.
