508B In Stock

The 508B by Newport is a Current Loop Indicator that is designed to integrate with process signals and provide precise digital displays of various parameters, including but not limited to level, temperature, flow, and pressure. This indicator is designed to operate with remarkable accuracy, offering the flexibility to display data in both percentage and engineering units. The 508B has user-friendly configuration options including input ranges, decimal point settings, and a dummy right-hand zero that can all be effortlessly adjusted using push-on jumpers. For those seeking precise calibration, the zero and span can be finely tuned with 25-turn potentiometers.

The 508B has minimal power requirements, drawing power directly from the current loop with a mere 2.5 V drop or 2.5 mW at 1 mA. Moreover, it boasts electronic isolation from its casing, rendering it impervious to most electrical noise sources commonly encountered in process-controlled environments. In terms of current tolerance, this indicator can withstand up to 250 mA in the forward direction and 1000 mA in reverse, ensuring robust operation. Designed with durability in mind, the 508B features low mass construction and multi-point circuit board support, providing exceptional resistance to vibration and shock. Its die-cast build, complemented by a sturdy polyurethane paint finish and a full fluorosilicone gasket, guarantees a virtually waterproof enclosure.
