Analog Input Batch Controller

TEK-BATCH 7900A SERIES ANALOG INPUT BATCH CONTROLLER

The Tek-Batch 7900A is an analog input (4-20 mA, 0-5 V, 1-5 V, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch^® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The Tek-Batch 7900A includes a 24 VDC power supply to drive the flow meter and can be equipped with up to four internal relays and a 4-20 mA analog output.
