Lutron TR-IR420 – Infrared Temperature Transmitter

Lutron TR-IR420 is an infrared temperature transmitter featuring analog outputs ranging from 4 to 20 mA, where 4 mA corresponds to 0°C (32°F) and 20 mA to 300°C (572°F). It has a fixed emissivity of 0.95 and a D/S (Distance/Spot) ratio of 7:1. The power supply requirement is DC 9V to 30V, with a maximum output load of 200 ohms. It comes with three wires: red and bare wires for power supply, and black and bare wires for the 4 to 20 mA output. The output temperature ranges from 0 to 300°C (0.053 mA/°C) or 32 to 572°F (0.028 mA/°F). The transmitter is designed for tripod fix nut mounting and has dimensions of 160 x 92 x 45 mm.
