Photovoltaic relays

Our photovoltaic relays (PVR) are remotely controlled switches (on/off) with complete galvanic isolation from input to output

anchor

Overview

The operating parameters of PVRs are ideal for switching low-level signal loads in instrumentation and data acquisition to medium-power loads in industrial controls and process automation, i.e., from microvolts and microamps to 400 V (AC peak or DC) and up to 6.0 A of load current at a contact resistance as low as 15 milliohms

Key Features

  • Linear AC/DC operation
  • Do not generate sparks
  • Positional insensitive
  • Stable contact resistance

About

Details of photovoltaic relays

?PVRs utilize our power MOSFETs or IGBTs as the output switches, driven by an integrated circuit photovoltaic generator. The output switch is controlled by radiation from a GaAlAs light-emitting diode (LED), which is optically isolated from the photovoltaic generator. This isolation provides users with protection from electrical shocks and protects electronics (such as microprocessors) from damage from high-voltage spikes.

Key features

The important key features of photovoltaic relays include a comprehensive portfolio of 1 Form A (single channel, normally open) and 2 Form A (dual channel normally open) relays, compact solutions available in DIP and SMT packages, high input sensitivity, load voltage range from 20 V to 400 V, up to 4 A AC load current and ESD tolerance with up to 4000 V human body model and up to 500 V machine model. MOSFET-based SSRs offer very low on-resistance and high-off-state impedance with switching times as fast as 150 ?s and IGBT-based SSR PVX6012 offers a high load current in the PDIP14 package.

Key benefits

Key benefits of photovoltaic relays are, among other things, complete galvanic isolation from input to output, compact solution, and low-power consumption, solid state reliability with long operational life, bounce-free and silent operation, fast switching speeds, insensitivity to stray electro-magnetic fields and to normal levels of shock and vibration, and UL508 certified up to Viso = 4 kV(rms) for 1 min.
