Class I, Zone 1 display that can power and control a Class I, Zone 0 or Class I, Zone 1 sensor, with optional connection to external monitoring network.
Self Contained, Intrinsically Safe Monitoring and Control System
An MDI can be paired with an Intrinsically Safe sensor to create a simple and complete monitoring system for hazardous locations. No IS barriers or outside connections are necessary.
Power Conservation Applications
The MDI's Timed Interval configuration lets you set the amount of time both the MDI and the sensor it is controlling are powered up. Less time ON means longer battery life.
Additional Monitoring Options
With the Auxiliary Connection option, an external Modbus system can be connected to "sniff" the MDI. This connection does require an approved IS barrier.
