The OMEGA[®] 4200A Series is an ideal controller for RTD applications. This quality-built linearized instrument is available in both 1.0° and 0.1° resolution models. Higher accuracies, accuracies 5 to 10 times greater than the typical 1% meter indicating controller, are achieved through a unique linearizing technique.
## **Specifications* RTD Input**

**External Lead Wire Resistance Effect:** 0.1% span up to 10 Ω per lead wire leg **Sensor Break Protection:** Built-in, upscale on open sensor
## **Calibration Accuracy:**
## **1.0° Resolution Model:**
±0.1% of span ±1 digit
**0.1° Resolution Model:**
±0.2% of span ±1 digit **Stability:** 0.1% for 30 to 130°F, 0.1%, 10% to 15% line voltage **Common Mode Rejection:** Maximum error ±1°C with 240 V, 60 Hz applied as common mode signal between sensor input and chassis ground
**Series Mode Rejection:** Maximum error ±1°C with series mode signal of 100 mV peak-to-peak @ 60 Hz
## **Control Output**
## **1st Setpoint**
## **(Adjustable Time Proportional):**
**Relay (Standard Model):** SPDT relay 7 A resistive @ 120 Vac, 5 A resistive at 240 Vac
