Why don't you include a power supply with your products?

Quick Answer: Most of our products are sold as components which are typically used as part of a larger monitoring or control system. Rather than using separate power supplies for each component in the system, it is usually cleaner and more convenient to use a single power supply to power multiple devices in the system. For this reason, we sell our power supplies separately. Example: If you install one WebRelay™ and two Five Input Modules™ right next to each other, rather than having three power supplies, you can use a single power supply to power all three units which offers a nicer, more compact installation.
