Product information
Product information
Instructions for accessories
ACT20M-RTCI-CO-(E)OLP-S
Configurable passive signal converter for temperature measurement of PT100, 2-, 3-, 4-wires and
thermocouples type J and K.
The 6.1 mm wide ACT20M-RTCI-CO-(E)OLP-S signal converter is output-current loop-powered and suitable for
converting and isolating RTD and TC 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).
On the ACT20M-RTCI-CO-OLP-S the input/output channel is completely galvanically isolated with 2.5 kV.
The ACT20M-RTCI-CO-EOLP-S does not have any galvanic isolation.
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.
Power is supplied directly on the module via the output-current loop.
