Overview:

Clean up your wiring with an MSD Solid-State High Current Relay Block. This high current module takes the place of 4 standard relays and eliminates unsightly wiring. Four independent channels can be activated using either power or ground. Each channel is capable of handling up to 35 Amps of continuous current, providing up to 140 Amps of power. It also has the capability of Pulse Width Modulation (PWM). With a PWM input, you can control the output at a rate of 15 hertz and a duty cycle of 50-90%. Controls electric fans, water pumps, nitrous solenoids, auxiliary lighting and any other electrical accessories that would normally require a relay. LED status indicators ensure proper wiring and operation of each channel. Should a problem arise, the relay block has built-in automatic over-temp, short circuit, and overload protection, as well as a channel reset. The solid-state high current relay can easily be mounted using the supplied hardware and mounting tabs that can be rotated 90° to accommodate various mounting locations.

Dogs love these sweetpotato treats
Flavor Name: Sweet Potato, Size: 2 Pound (Pack of 1)
We dogsit grandkids’ dogs. Grandson sent a half bag of these and a full bag of another brand of Sweetpotato treats. The dogs actually spit out the new brand and refused to eat them. We have a tiny dog, a middle dog and a big dog. They ALL went crazy over thesetreats. They are very healthy treats. Works for all size dogs. The bag tells how much to feed each size dog? Grandma was the treat lady so I won big time ..We were worried cuz we had never watched the dogs before. We actually had a great time and hated to see them go.They really looked forward to their treat time. 😋
