MTL4521英國MTL原裝進口,假一罰十.大量現貨,歡迎選購!!!

The MTL4021S enables an on/off device in a hazardous area to be
controlled by a volt-free contact or logic signal in the safe area. It can
drive loads such as solenoids, alarms, LEDs and other low power devices
that are certified as intrinsically safe or are classified as non-energy
storing simple apparatus. Provided that 24V dc is applied to the override
input, the solenoid/alarm can be operated by the control input.
However, if the 24V dc signal is removed, the solenoid/alarm is turned
off. Earth fault detection can be provided by connecting an MTL4220
earth leakage detector to terminal 6.
