The Multichannel Stream Selector is a Digital Logic Sequencer for directing multiple streams to the Analyzer. The instrument performs sequencing logic and controls stream selection of up to six streams in analytical applications, using control Relay outputs for each stream, which can be synchronized by external Pulse or Timer. The instrument has a bright OLED display with 20 characters x 4 lines format which shows the process status and various parameter settings.

The Stream Selector accepts 4 to 20 mA DC current signal from the Analyzer and provides up to 24 nos. of potential free and powered relay contacts with LED indications on the front panel to indicate the status of various processes. The system is designed to control stream selection of up to six-stream system using its Relay outputs and synchronized Input or Timer. It also generates Sample and Hold analog outputs for each channel in the cycle. The instrument provides analog retransmission signal outputs corresponding to each stream, besides providing sample and hold of the outputs. The STL-96 instrument operates in both, the Auto and Manual modes. LED indications are provided for Status of the Streams, indication of Low and High alarms and Status indication. The instrument is available in DIN standard enclosures and operates on 90 to 270 V AC mains universal power supply.
