توضیحات محصول

The MTL4525 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 nonenergy storing simple apparatus. The MTL4525 allows a second safe-area switch or logic signal to be connected that enables the output to be disabled to permit, for example, a safety system to override a control signal

Number of channels :One

Location of load: Zone 0, IIC, T4–6 hazardous area if suitably certified Div.1, Group A, hazardous location Minimum output voltage: Equivalent output circuit

Hazardous-area output :Minimum output voltage: 7.8V at 48mA
