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** 

**Type:** 100 Ω platinum; alpha = 0.00385 (DIN curve) **Configuration:** 3 wires 

**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 

**Option “T” (Triac):** Solid state plug-in triac rated 1 A holding and 10 A in-rush 

**Option “F” (Current Proportional):** 4 to 20 mAdc into 1000 Ω maximum 

**Option “DC” (DC Pulse):** 20 Vdc 

_*****[ Specifications and configurations subject ] to change as advances in technology allow._ 

**Proportional Band (Gain):** 0 to 3% of span, or on/off; selectable **Manual Reset (Offset):** Adjustable **Cycle Time:** Automatically adjusts with load requirement to give least wear with minimum ripple (10 s minimum) 

## **Display and Indications** 

**Temperature:** Filtered LED, 3 or 3[1] ⁄2 digits, 2 readings per second update; readability is 1.0° or 0.1° (°F or °C), depending on model 

**Setpoint:** By spring loaded switch, first or second setpoint is displayed in place of temperature; setpoint adjusted by 25 turn potentiometer; 1.0° or 0.1° setability **Outputs:** LED indication for both first and second setpoints; LED are “on” when output drive signal present; “on/off” indication on relay and triac model; proportional intensity for option “F”
