Modbus I/O modules for networkable and standalone monitoring and control applications deliver new and flexible I/O options to users and broaden the company’s I/O product range for contractors, systems integrators, end users, and OEMs. The Ui28_PC2 can be used for monitoring sensors and metering devices. Users can efficiently monitor temperature, humidity, current, and other status points for building automation, energy management, and other applications. It has 28 inputs, giving customers an easy way to gather data from a large number of sensors with a single device. It is a universal I/O device featuring two high-speed, 32-bit pulse counters. According to the manufacturer, Ui28_PC2 can help businesses and residential customers more easily track consumption tied to electrical, water, and gas usage, since most utility meters have a pulse output. Businesses also can use it to monitor subcircuits, which can help customers measure usage specifically tied to certain elements, such as lighting circuits, in addition to using the pulse counters to measure a building’s total energy usage as recorded by the main utility meter. The Ui16_R5 reduces the input count and adds five output relays. It can be used for monitoring and control of multiple points. The output relays enable the control aspect and can be used network-wide to easily turn lights on and off, activate or deactivate alarms, or fire up the air conditioner or heating system to address room temperatures. The device also features a heartbeat timer so that it can continue to operate standalone in the event of network failure, ensuring that the building remains comfortable and equipment continues to operate. Both devices are compact and rail-mountable, and capable of working with 12-24 vac or dc power supplies.
