EMCO EE-602 Remote Temperature Indicator (ROTI/RWTI) is a digital temperature indication instrument designed for remote monitoring of transformer oil and winding temperature. It receives a resistance signal from the transformer’s OTI/WTI and displays the corresponding temperature on a clear 3-digit, 7-segment LED display. The EE-602 supports 0–440 Ω and 0–2.8 kΩ inputs, with optional 4–20 mA or PT-100 input and optional 4–20 mA output for SCADA/control-room integration. It operates over a temperature range of 0–150°C, features microcontroller-based circuitry, full-scale adjustment and test/normal operation, and has a standard 92 × 92 mm panel cutout.
 
Applications: Transformer OTI, WTI, remote oil temperature indication, remote winding temperature indication, RTCC panels, control panels and SCADA temperature monitoring.
Available as: ROTI (Remote Oil Temperature Indicator) and RWTI (Remote Winding Temperature Indicator).
