ACT20M-RTI-AO-S Details


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 the power supply are completely galvanically isolated with 2.5 kV. 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 supply can be installed easily and quickly via the CH20M rail bus. The power is supplied via any ACT20M module (up to 10 devices) or a separate ACT20 supply module (up to 200 devices).
