Industrial D1S-2R-24 S 5538 Temperature Controller Module

The Sestos D1S-2R-24 is a digital temperature controller module designed for reliable temperature regulation in industrial heating and cooling processes. The -24 variant is powered from 12–24 V AC/DC and accepts a K-type sensor input for temperature measurement, with a relay-style control output rated up to AC 250 V and 3 A (NO/NC) for resistive loads; some listings also indicate configurations that provide a 4–20 mA current output. Identified as D1S-2R-24 with BIN 4.5.4 and S/N 5538, this unit is sold as used/tested by vendors, consistent with a “sold as seen” condition in many listings. Typical applications include process control on ovens, dryers, heat exchangers, and other temperature-critical equipment used in manufacturing lines where precise temperature management is essential. As part of the SESTOS D1S digital temperature controller family, it is commonly chosen for straightforward, programmable temperature regulation in industrial settings.
