DW3 Description

Short technical summary and product information.

The DW3 wire breakage detector by POSITAL FRABA is engineered for reliable line monitoring of mechanical switch contacts, including N/O and N/C types. It detects wire breakage and short circuits, signaling proper connection status through a potential-free electronic contact that opens upon failure. The switch condition of the monitored contact is also indicated via a potential-free electronic contact and a relay contact.

 

This module requires an auxiliary power supply of 24V DC/AC and is easily mountable on a 35mm cap rail (TS35). It features a narrow design with a width of 17.5mm. The DW3 is suitable for monitoring alarm contacts in fire detection systems and other applications requiring robust wire connection integrity.

 

Key technical specifications include a supply voltage range of 19.2-30VDC or 18-28VAC, with a current consumption of less than 1VA. It supports one N/O contact input and any number of N/C contacts. The device offers both electronic and relay outputs for signal and malfunction messages, with relay contacts rated up to 250VAC/30VDC at 2A.
