ABB LDSTA-01 I/O Module

ABB LDSTA-01 I/O Module 

The ABB LDSTA-01 offers flexibility, stability and reliability in a single cost-effective unit. The modules build on the foundations of the 1900 Series, offering the same measurement benefits and a range of new and enhanced operational features to maximise flexibility in configuration and use applications. In addition to fault and calibration history, all units offer NAMUR-compliant relay functionality, allowing the remote transmission of two concentration alarm levels and messages for required maintenance, ongoing service and instrument faults. Comprehensive Modbus protocol allows remote communication and device interrogation via RS485, and an optional Ethernet connection is also available. Auto-verification and auto-calibration features give the user complete flexibility for unmanned or remote operation, or the use of trend information to generate maintenance and reliability plans. Stainless steel pipework, automatic range change, fixed background gas compensation and measurement filtering are now also available as standard.

The ABB LDSTA-01 introduces three options designed and implemented by Servomex that not only significantly raise the standard of comparable units, but also offer potential cost savings in installation and operational performance. The fully heated sample chamber removes the requirement for a sample conditioning system for all samples with dew points up to 50 degrees Celsius. Sample conditioning failures of up to 80% in comparable equipment are a major cause of unplanned downtime. The heated sample chamber design reduces the risk of downtime by removing the cooler, dryer and other conditioning devices. This design reduces operating costs as well as initial system and integration costs, making it particularly well suited to the measurement of ‘wet’ gases.
