Power-io products -- solid state relays, solid state contactors, motor starters and I/O modules

New "H" Family of hockey puck solid state relays for AC switching applications from 1-90 amps. These relays include a clear safety cover and the Maximum Surge Survival™ technology:

    1-90 amp, AC or DC activated solid state relays for switching AC loads
    SSR heat sinks, thermal transfer pads, MOVs, parts, pre-installed options
    I2T fuses, semiconductor fuses and din rail fuse holders

"HDD" Family of hockey puck solid state relays for DC switching applications. These relays include a clear safety cover, the Maximum Surge Survival™ technology, RoHS, CE, and Made in the USA. DC switching is common for solar, vehicle, and alternative energy applications, using mosfet or IGBT technology. Switching can be any speed up to 20kHz PWM:

"C" Family of din rail contactors for applications up to 100 amps. Two pole switching or individual single poles; Maximum Surge Survival™ technology; and flow through wiring. The universal, modular design replaces mechanical, mercury or lighting contactors in industrial, municipal, or military applications.

    
    up to 100 amp per pole, DC activated, + diagnostics feedback output
    up to 100 amp per pole, 0-10 VDC analog activated, + diagnostics feedback output. This analog input version provides normal high speed on/off/on/off based upon a 1 second time period, OR it provides electrically clean, zero-crossing, high speed performance based upon 3 half sine waves and adding additional ON or OFFs.

Schneider Zelio 3 phase solid state relays for AC switching applications from 1-25 amps, per phase.

    Schneider 3 phase solid state contactors

The following product lines have been discontinued, primarily due to changes in RoHS lead-free requirements. Please contact Power-io for information about replacement options.

"IO" family of solid state I/O Modules: monitor AC or DC as inputs, or generate 0.1 - 3 amp outputs. Smallest size, fused outputs, 4000 volt isolation. Compatible with PLCs, PCs, TTL, and most controllers:

    Input Modules
    Output Modules

Mini "D" Family of din rail relays for applications from 1-40 amps. The Mini "D" family includes: an integral heatsink, recessed finger-safe terminals, and the Maximum Surge Survival™ technology:

    25 and 40 amp, AC or DC activated
    25 and 40 amp, analog 4-20mA activated
    Potentiometer input, pot input, manual station, manual % power controller

Three phase "D" Family of din rail relays for applications from 1-35 amps per leg. Ideal for switching 2 or 3 legs of a three phase load (delta, star, or wye loads).

    1-35 amps, two or three legs, AC or DC activated
    1-35 amps, two or three legs, analog 4-20mA activated
    Potentiometer input, pot input, manual station, manual % power controller

"D" Family of din rail relays for single-phase applications up to 100 amps. These models include: large finger-safe power terminals for 3 - 8 AWG wires; a built-in, replaceable, I²T fuse; and 2 red diagnostic LEDs for fuse open and over-temperature shutdown.

     up to 50 amp, 75 amp, or 100 amp contactor; AC or DC activated

Older "H" Family of hockey puck solid state relays for AC switching applications from 1-75 amps. These relays include a clear safety cover and the Maximum Surge Survival™ technology:

    1-75 amp, AC or DC activated solid state relays for switching AC loads
