Programmable load cell amplifier is an intelligent product designed to help the user by bringing ease of Onsite settings. The user has to feed appropriate parameter settings using Keypad and Display provided on the front panel. The S/W controlled self tuning feature of the product takes care of accurate calibration of the unit. Keypad controlled TARE and SPAN setting allows even an inexperienced user to tune the product on site.

Inputs from wide variety of Load-cells having response ranging from 0.5mV/V to 16mV/V are Field configurable. Response time is configurable to suit the application at hand. Analog output (0-10V/4-20mA) is provided. Control outputs (Relays 2 nos.) allow set point control feature. RS-485 MODBUS Communication interface enables remote configuration and data retrieval.
