GI Module MTL4021 DO

The MTL4021 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. By connecting a second safearea switch or logic signal, the output can be disabled to enable, for example, a safety system to override a control signal. Earth fault detection can be provided by connecting an MTL4220 earth leakage detector to terminal 6.
