Shinko Electronics JCS-33A-A Temperature Controller

Shinko Electronics JCS-33A-A is a compact, microcomputer-based digital indicating temperature controller designed for industrial machinery, machine tools, and measuring equipment. It provides a four-digit PV (process value) and a four-digit SV (set value) display on the front panel, with PV digits shown in red and SV digits in green to clearly distinguish the measured temperature from the setpoint; this visual layout supports quick monitoring and adjustment in busy control panels. The unit fits a 48 x 48 mm front panel footprint, with an approximate depth of 106 mm, making it suitable for space-constrained instrument panels. A relay output handles heating or cooling control and is typically rated for up to 3 A at 250 V AC for resistive loads (and lower for inductive loads), aligning with common industrial applications such as hot plates, ovens, or other process heating. The JCS-33A-A is powered from 100–240 V AC (50/60 Hz), a universal mains range that covers most global installations, and, in the broader JCS-33A family, supports use with heating elements, SSRs, or a 4–20 mA current loop as part of temperature regulation setups.
