Description
Waveshare Industrial 4-Ch PWM Output Module Modbus RTU RS485, Adjustable Frequency & Duty Cycle, Modbus RTU PWM Output 4CH1. This product is an industrial standard isolated RS485 to PWM pulse output module. Four channels of frequency and duty cycle are independently adjustable. It adopts Modbus RTU protocol and includes built in protection circuits such as power isolation, magnetic coupling isolation, self recovery fuse, and TVS. 2. The output uses high speed optocoupler isolation, and the output high level voltage can be selected via internal jumpers. 3. Four channels
1. This product is an industrial standard isolated RS485 to PWM pulse output module. Four channels of frequency and duty cycle are independently adjustable. It adopts Modbus RTU protocol and includes built-in protection circuits such as power isolation, magnetic coupling isolation, self-recovery fuse, and TVS.
2. The output uses high-speed optocoupler isolation, and the output high-level voltage can be selected via internal jumpers.
3. Four channels of PWM pulse output with frequency and duty cycle independently adjustable.
4. Supports setting device address (1 to 255) to cascade multiple devices via the RS485 bus.
5. On-board voltage regulator chip supports wide voltage supply from 7V to 36V.
6. On-board integrated power isolation provides stable isolation voltage; the isolated end requires no additional power supply.
7. On-board integrated magnetic coupling isolation enables signal isolation, with high reliability and strong anti-interference capability.
8. On-board self-recovery fuse and TVS (Transient Voltage Suppressor) effectively suppress surge voltage and transient spike voltage in the circuit, protecting against overcurrent, overvoltage, lightning, and static electricity.
9. Built-in watchdog ensures stable output without crashing.
10. Rail-mounted enclosure design, compact size, easy installation.
11. External 3 LED indicators for convenient viewing of power status and signal transmission/reception status.

A Game-Changer: Camco Deluxe Poop Tote Review
Size: 36 Gallon, Style: Heavy Duty (2 Wheel)
The Camco Deluxe Poop Tote is a standout choice in the market, offering exceptional build quality, comprehensive features, and impressive functionality. What sets it apart is not just its superior design but also its surprisingly affordable price tag. As someone who previously owned a Thetford unit, I can attest to the significant difference in quality. The Thetford unit, while well-made, fell short in design by lacking a crucial component - the drain valve for the tote. Even after investing in the missing part separately, using it remained a source of frustration due to its flawed design.In stark contrast, the Camco Deluxe Poop Tote comes fully equipped with a well-thought-out design that prioritizes practical real-world usage. One particularly thoughtful feature is the inclusion of front wheels, which make a noticeable difference, especially for older users. These wheels significantly reduce the effort required to pull the cart towards your tow vehicle, enhancing the overall user experience.

Well made and useful. Wish the handle was more comfortable though
Size: 21 Gallon, Style: Heavy Duty (2 Wheel)
Like most people I am using this tote to unload my camper’s grey water tank while camping. It is well made and good quality and has worked very well. They also provide all of the fittings you might need. The only thing I don’t like is the main orange handle. The front side it solid but the backside is ribbed or hollow. When the tank is full, and I use the handle, the ribbed side kinda hurts my hand. A work glove solves this issue though but I wish the handle was solid.

Sturdy portable tank
Size: 15 Gallon, Style: Heavy Duty (2 Wheel)
Strong portable waste tank. It is pretty tall (about 12 inches plus the height of the elbow). I had to raise my trailer jack most of the way up to raise the waste outlet high enough to facilitate draining. Once I figured that out, it works like a champ. The large wheels really help with transporting the full tank across my yard. Camco has included all the accessories needed to complete the job. The 15 gal capacity is pretty small...so you may have to split your job into multiple trips, but for as often as I might need it, it'll do.
