Description
The MDI Intrinsically Safe Modbus Display provides a local display in a Class I, Zone 1 hazardous area that can monitor and control a sensor in either a Class I, Zone 0 or Class I, Zone 1 area. The MDI can supply power to the sensor it controls, creating a complete monitoring-and-control system within the hazardous area.
The MDI can also be connected to monitoring equipment outside the hazardous area through an IS barrier, allowing readings from the sensor to be seen across the monitoring or control network. Modbus control and display in hazardous areas. 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.
