The 8940-450-DC, 8941-450-DC and 8942-450-DC from Calex are low cost isolated thermocouple solutions ideal for applications where single point, isolated RTD signal conditioning is required. This 8940 series is suited for use with 100, 500, and 1000 ohm platinum RTDs with a temperature range of -50°C to 450°C and is designed for use with 2 or 3 wire TRD configurations. All models employ linearization, three-wire compensation, as well as provide complete three-way signal isolation. The input is isolated from the output and both are isolated from the supply voltage. All models are housed in a plastic case with a built in DIN Rail mounting foot.
