MTL3043 DC ISOLATOR, 1/40mA for fire and smoke detectors. Brand new hot sale in stock with 1 year warranty 100% New&Original
The MTL3043 is similar in principle to the MTL3042, but with a higher current range for use primarily with fire and smoke detectors or similar high integrity switched-resistor systems. In these applications the unit shows, by a change in the safe-area current, when one of the detectors across the 2-wire circuit in a hazardous area has been triggered. With a suitable receiving instrument in use, line short circuits do not give a false alarm and – if an end-of-line resistor is added to the system – open circuits do not give the operator a false sense of security. Further, the isolation feature eliminates the multiple earths that can arise in conventional barrier systems when the supply is earthed, and permits earth faults in field wiring to be detected and cured while the unit continues working.
