Expanded line of AC and DC sensors for IoT applications

L-com has expanded its line of AC and DC sensors. Ideal for IoT applications, the new AC and DC sensors protect electrical systems from over-current, short circuits and inefficient and costly energy usage. The devices are created for usage in building and facility management systems, including HVAC, electric fans, electric motors, electric pumps, industrial automation, and machine building applications.

The new AC sensors and over-current protectors are offered in varied detection ranges from 5A to 100A. They have analog and relay outputs, and some have an RS485 output. There are versions with an output delay timer. Available options for DC supplies include 5V, 12V and 24V. They use CT technology. Two AC sensors are provided with ten input channels and monitor all ten simultaneously.

The new devices are offered in various detection ranges from 1A to 70A. They have analog (0V to 5V), relay outputs, and adjustable threshold levels. Some versions are provided with a display. Selected models have an external shunt resistor that activates a relay if the current exceeds a preset value.

The sensors offer compact sizes and low power consumption. They feature screw-type terminal blocks for simple field termination and a removable PCB for a panel or other enclosure. They mount to a standard 35mm DIN rail, a wall or a panel.

“These new AC and DC sensors not only give our customers insight into how their electrical systems are operating but protect their systems from over-current and short circuits and improve their energy efficiency,” said Tim Houghton, senior product line manager.
