Temperature guard for Pt100/Pt1000 probes and thermocouples of the types J, K, N, S.
Simple programming, 2 alarm outputs (SPDT). Peak value indication for minimum and maximum measured temperature are stored in the background and can be read out from the display at any time.
Features:
- Inputs Pt100/Pt1000, thermocouples type J, K, N, S
- Measuring range programmable
- Plaintext supported programming by graphic display
- 128 x 64 pixels LCD with white back-light
- 2 alarm outputs, relay SPDT
- Galvanic isolation between input/output/supply voltage
Note:
For safety applications please use the safety temperature limiter STL 50, certifed to DIN EN 14957 and DIN EN 61508 SIL2.
