The Piccolo RTU is a small remote terminal unit (RTU) that consists of an electronic board and a 3-way latched solenoid, packed in an IP65 plastic housing. The Piccolo RTU is connected serially on a two-wire standard cable at a distance of up to 10 kilometers (6.2 miles) to an IRRInet single-cable module. It provides energy to one latched solenoid and receives two digital inputs.
The Piccolo RTU is powered from the communication cable (no need for an additional power supply), which is connected to the single cable module mounted in the IRRInet unit. Up to 63 Piccolo RTUs may be hooked up along the cable.
