Tender Specification Sheets

Short specification

Ex- temperature transducer for RTD-/ TC temperature signals and DC current signals1-channel temperature transducer in 22.5 mm width with external power supply,for capturing and isolating RTD- / TC- sensor and DC current signals (0(4)...20 mA) from Ex zones 0,1,2. The output can be operated in the safe zone either as an active signal (0(4)...20 mA) or as a passive 4...20 mA current loop. Status and error messages are available via a relay contact (NO).The component can be configured using standard FDT/DTM software.
