The circuit is designed to detect a break in the continuityof the detection circuit and ground failures.On position “PTC”, line or sensor fault is also detected.Reset after failure detection: Press reset button or interrupt supplyvoltage for >200ms.1 PTCSensor29 8 7 5 3ThermoSwitch4alokSensor resistance RokSensor wire RmaxError-detection RfailSensor supply U5-7Sensor supply 5maxData at Tamb. = 20°C100..1800 ; 0..180020Rfail >220015V / Rsens ∞≤3mAA210 11 6 1 A12+Switching current/voltageSwitch ratingMechanical switching cycles5A 250VA1250VA/...180W30x10 6Voltage tolerancePower consumptionAmbient temperature–15/+10%≤5VA–25...+60°C75Order no.Accessories50/60HzUC(AC/DC)SocketRetaining clipC11AHF-24TSR19/AC230VTSR19/AC115VTSR19/UC24-48VFrontpanel mounting: HF-23C11A38The TSR19 replaces the types TSR17 and TSR18.Socket and Accessories: Page 97132 KAT2008This edition replaces all previous issues.Availability, errors and specifi cation subject to change without notice.COMAT AG • BERNSTRASSE 4 • CH-3076 WORB • SCHWEIZ www.comat.chTel. +41 (0)31 838 55 77 • Fax. +41 (0)31 838 55 99 • info@comat.ch
