Overview of the Monarch DC1250 2-Channel Paperless Data Recorder
The Monarch Instruments DC1250 2-Channel Paperless Recorder is a feature packed data acquisition system that offers two universally configurable inputs for measuring DC voltage, DC current, thermocouples, and RTDs along with frequency and pulse inputs. Included with the DC1250 are four internal alarm setpoints, two alarm relay outputs, and one digital control input. With a maximum storage rate of 100 samples per second, the two channels can capture short duration process signal anomalies. The DC1250 uses a highly reflective twisted nematic LCD with a bright LED backlight. The interface can be configured to display real-time data in a digital or trend format. Configuration is done using an easy-to-follow intuitive menu system. When purchased with the optional Ethernet port the recorder can be accessed remotely over a standard 10/100BaseT network.
