The ProVu PD6310-WM is an NTEP® certified, pulse input (NPN, PNP, TTL, switch contact, sine wave, etc.) digital batch controller specifically designed for single and multi-stage batching applications which has been certified as a Weighing and Measuring device. These versatile NTEP certified batch controllers provide excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and intuitive front panel buttons for simple operation and menu navigation. This Weights and Measures approved batch controller is equipped with a mechanically secured, tamper-proof, programming lockout feature.
