The DTC series of PID Controllers offer front panel selection of all operating functions except for some input types. The DTC series offers more flexibility in controls, and more control output options to DigiTec's PID controller line. The DTC offers optional Motorized Valve Control, RS-485 Communication, Heater Current Monitoring, or Remote Setpoint. Auto-tune control will monitor the system output response and after 3 cycles it will automatically calculate and replace the PID constants with optimal process control parameters. Controller Accuracy: For TC inputs: 0.25% of F.S. ±1 degree For...

The Digitec D2040 loop-powered display is a 3-1/2 Digit, short depth LCD display. The display can indicate level, % flow, or pressure in a 4-20 mA process loop. The D2040 also is well suited to be used as a remote display. User adjustable scale (gain), offset and decimal point allow immediate calibration of measurement being displayed. PROCESS APPLICATIONS • Level • Pressure • Flow 3-1/2 Digit Loop-Powered Meter Current loop measurement of 4-20mA and 10-50mA DISPLAY RANGE • 3-1/2 Digit full-size LCD 0.6" high • 1/8 DIN Anodized Aluminum Case POWER REQUIREMENTS Loop powered; voltage drop...

The Digitec D2080 is a loop powered indicator that measures, displays and totalizes the current in a 4-20 mA circuit. Although the instrument is loop powered, it only produces <3.5 V drop allowing it to be used in series with almost any 4-20 mA application. Modular accessories enable the user to select the lowest cost configuration while retaining full interchangeability between instruments. Optional high alarms provide two isolated open drain outputs which may be independently programmed with a high trip point. When an alarm is tripped, the alarm and current reading alternate on the...
