Evaluation unit TK-315

The TK-315 limit comparator can be used in conjunction with our TK-30... continuous level sensors with 0(4)...20 mA or 0...10 V output signal for level control/measurement. Special characteristics Control & detection of fill levels via 0(4)...20 mA or 0...10 V input signal Digitally adjustable switching points Free adjustment of the 4 limit values over the entire measuring length Further product information Where more than 4 limit values (NO-contacts) are required, individual limit comparators can be connected in parallel to form a functional unit. All limit values can be adjusted freely over the entire measuring length. The signal at the input of the limit comparator is compared with switchpoint values which can be adjusted digitally by the user. If this limit values are exceeded or not reached, the respective isolated output contact operates. The output relays of the TK-315 limit comparator operate on an open-circuit current principle. The measuring signal is indicated digitally in %. The TK-315 possesses a wide range power pack and can be operated by 24 V DC to 230 V AC .
