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).
The configurable WTS4/WTZ4 PT100 temperature signal converter with external power supply in 12.5 mm width, for recording and transforming PT100 sensors in standardised DC current and voltage signals.
2-, 3- and 4-wire PT100 sensors can be connected on the input side. The temperature ranges can be selected using DIP switches. The input and output circuits are not electrically isolated from each other. The output is used for the 24 VDC power supply.
The WTS4/WT/4 Thermo comes with either a screw or tension-clamp wire connection. The 24 VDC supply voltage can be bridged using pluggable ZQV 2,5N jumpers on the module side.
