Shinko ACD-18A-R C5,T6598 Multi-Range Controller

The Shinko ACD-18A-R C5,T6598 Multi-Range Controller is a digital indicating temperature controller with a relay output designed for industrial process temperature control. It supports multiple sensor types, including thermocouples (K, J, R, S, B, E, T, N, PL-Ⅱ, C) and RTDs (Pt100, JPt100 with 3-wire configurations), as well as DC current and DC voltage inputs, enabling flexible integration with a wide range of temperature sensors. The unit’s relay output is rated to 3 A at 250 V AC (resistive load) and 1 A at 250 V AC for inductive loads (cosφ = 0.4), with an electrical life around 100,000 cycles, and it comes in a compact 96 × 96 mm front-panel footprint (depth ≈ 110 mm) weighing about 460 g. The C5 option adds serial communication capabilities, and the model is identified by the T6598 designation as part of Shinko’s ACD/ACR digital indicating controller families, which also include ACD-13A and ACD-15A variants. The display features an 11-segment PV readout (5-digit) with backlighting, plus SV/MV/TIME readouts, and a 22-segment LCD bar graph for process monitoring. This makes the ACD-18A-R suitable for precise temperature control in heating and cooling loops across industrial equipment and systems.
