4-CHANNEL MULTI-PURPOSE MONITOR WITH FLEXIBLE POWER OPERATION

The ISM-4 industrial status remote monitor is ideal for applications where flexibility of voltage measurement ranges is paramount.  With four surge resistant analog measurement channels that can be independently configured to accurately measure voltages from +/-100mV to +/-200V, the ISM-4 is both versatile and rugged. This versatility makes it the ideal choice for any industrial application that requires multiple measurement options including field sites, in-plant equipment, or other remote assets requiring diverse voltage measurement capabilities where dependable real-time monitoring is critical.

The ISM-4 has the option to be powered by an external source like AC line input, a generator, or solar power, or it can function solely on its lithium battery where power is unavailable or unreliable. That gives the ISM-4 incredible adaptability to report from sites that were previously difficult to monitor. Coupled with the Elecsys cloud-based web-interface, the ISM-4 provides both flexible configuration features and powerful reporting capabilities. And like all Elecsys products, the ISM-4 is proudly made in the USA.
