UTNH23A

The UTNH23A consists of a leak detection controller in a DIN rail mounted enclosure and up to 1500m of leak sensing cable. The controller is capable of detecting leaks and indicating their location as a distance along the cable from the controller.The LKC-1500 controller has an LCD and three pushbutton switches that allow the user to access the options menu and select from a variety of programmable functions. During normal operation, the display shows the system status or location of any leaks. The controller can be powered from 210-250VAC mains (105-130Vac, US version) or from 10-24Vac or 12-32Vdc via the low voltage power terminals.

The UTNH23A controller has a variety of process outputs including two SPDT relays for direct control of mains powered pumps, valves or alarms, provides an open collector transistor for connection to a Programmable Logic Controller (PLC), a Building Management System (BMS), or indirectly to drive additional valves or pumps via external relays, and finally remote monitoring and control via an RS485 serial communications port for remote monitoring. The controller is capable of detecting damaged or improperly terminated sensing cables and can assign relay and transistor outputs to respond to leaks or faults.
