Communication Devices

The PRD1000 is a multi-purpose, easy to use digital process meter ideal for level, flow rate, temperature, or pressure transmitter applications. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Its has a dual-line 6-digit display, advanced signal input conditioning, function keys, and Modbus RTU serial communications. The basic model includes an isolated 24 VDC transmitter power supply that can be used to power the input transmitter or other devices.

The analog input can be scaled to display the process in up to two different scales; for example the main display could indicate level in feet and the second display could indicate the volume in gallons. The two relays can be used for alarm indication or process control applications, such as pump alternation control. The upper display can be programmed to indicate PV, maximum (peak), minimum (valley), alternating maximum/minimum, one of two alarm set points, or Modbus input. The lower display can also be configured to display engineering units, set points, user defined legends, or simply turned off. There are three function keys available to the user. These keys can be programmed to trigger certain events (i.e. acknowledge alarms, reset max and/or min, disable/ enable output relays, or hold current relay states), provide direct menu access points, and more.
