Relay Output (optional) Screw terminals enable a remote "auto-tare" 5A SPDT dry contact relay function to compensate for non-zero dead weights and other sensor offsets (e.g. container Power Requirement weight or bridge imbalances). Alternatively, these 12 to 36V DC same screw terminals may be used to reset latched relay alarms. Approvals CE marked. UL, cUL listed. All these powerful features combined with Acromag's user-friendly configuration software, make the 851T a versatile device that's easy to use and maintain. Plus, a rugged, compact design makes it ideal for use out in the field, on the plant floor, or inside a laboratory.
