The ProtEX-MAX PD8-6310-WM offers all the functionality of the ProVu PD6310-WM as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It 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 convenient SafeTouch® through-glass buttons for simple operation and menu navigation without having to remove the cover. The Weights and Measures approved controller is equipped with a mechanically secured, tamper-proof, programming lockout feature.
