Configurable signal converter for PT100, 2-, 3-, 4-wire measurement. The 6.1 mm wide ACT20M-RTI-AO-S signal converter with external power supply for converting and isolating RTD temperature signals.
Input and output parameters as well as a fast conversion time of 30 ms or 300 ms can be configured via DIP switch. The ACT20M temperature converter detects sensor errors (short-circuit, cable break) and issues corresponding NAMUR signal limits at the output (configurable upscale/downscale).
The input/output channel and power supply are NOT galvanically isolated.
The ACT20M product family features high accuracy of < 0.05% of the measurement range, a large temperature range of -25°C (0°C)...+70°C, outstanding EMC characteristics and international approvals (cULus, ATEX Zone2, FM Div2, GL, DNV). This permits use around the globe in a wide range of applications.
The power is supplied directly on the module itself or via any ACT20M module (up to 10 devices).
Temperature converter, 2-/3-/4- wire RTD, Without isolation, 24 V DC ± 30 %
