Pyragon Loop Isolator

Pyragon Loop Isolator

 (2)
  • Signal Powered CMOS Circuitry
  • Precise Duplication of Input Signals
  • 4–20 or 10–50 mA, Same Unit
  • High Common Mode Rejection
  • 1500 VRMS Isolation
  • Mounts on Bulkhead or in 3" Conduit Box
Provides the Necessary Signal Isolation for Noisy Process Circuits
If your process signals are influenced by ground loops, high common mode noise, or other interference, you need the Transmation Model 10 Auto-Isolator. Requiring no separate power supply, Auto-Isolator operates efficiently from input signal current, and precisely retransmits the current applied to the input with an accuracy of ±0.1% of span.

Usable with milliamp signal ranges of 4–20, ...

Adtech Two-Wire Transmitters - 100 Series

 (8)

The ADTECH 100 Series Two-Wire Transmitters provide field mounted efficiency and ease of wiring in a compact package. The units convert sensor inputs to the industry standard 4-20 mA DC Two-Wire loop output for interface directly with PLC’s, DCS’s and process computers.

 Most units provide independent linearity equivalent to 14-bit digital accuracy and include user friendly features such as wide ranging and non-interactive zero and span controls. The compact mounting style allows high density mounting in new or existing field mounted or control panel enclosures.

 These units are designed for industrial (field) environments. The housing is made of ...

Adtech Loop Powered Indicators

 (4)

The Adtech LPI series of loop powered LCD indicators provide an ideal user configurable solution for process indication. The units accept a process input signal of 4-20 mA DC and provide a 3 ½ digit, 7 segment 0.5” LCD display.

The 4-20 mA signal may be from a two-wire output loop or an output of three-wire or four-wire transmitters. Power is derived from the input signal with no external power source required. The 3 ½ digit LCD may display 4-20 mADC (4-19.99) or engineering units such as ºC or ºF, etc. The output may also be displayed as 0-100%. Zero and span controls are provided by two separate infinite resolution potentiometers. Jumpers are provided for decimal point position and ...
