Digital Process Monitors Digimate 2317N ( 0,1 ,2, Etc.)
The Series DigiMate 2317N instruments are panel mounted Digital Process Monitors designed to interface with two-wire transmitters and other process control instruments. In addition to indication, they provide transmitter power, decimal selection and optional alarm or trip functions and are available in a variety of enclosures to suit the user's needs. These general purpose instruments can be tailored by the user, at site, to suit his range and alarm function requirements.
A DigiMate 2317N incorporates a 24 VDC transmitter power supply, a signal processing module and a precision 3½ dgt A/D converter to display the input signal directly in engineering units. It also provides upto four optional HI/LO alarms and incorporates Industry standard power options. The span, zero and alarm adjustments are accessible from the front after pulling the sliding chassis out without disconnecting signal or power to the instrument. All environment sensitive components are potted in epoxy for reliability. The Instruments are modular in their structure and are designed for better service-ability and are coated with varnish for protection against unfriendly environment.
