Mitsubishi Electric Corporation ST1Y2-TE2 Output Module

The Mitsubishi Electric ST1Y2-TE2 is a 2-point transistor-output module for the MELSEC ST Series digital I/O, delivering remote 24 VDC outputs over CC-Link or PROFIBUS-DP networks in distributed automation. The listing notes this unit is take-out and never energized in service. It drives common field devices such as solenoids, contactors, relays, and indicator lamps from each channel at up to 0.5 A per point (1 A common), with a maximum inrush of 4 A for 10 ms, and a fast 1 ms maximum ON/OFF response time. Each output uses photocoupler isolation, with a maximum 0.3 VDC voltage drop at 0.5 A and leakage current limited to 0.1 mA, and an integrated 4 A fuse protected by an ERR LED indicator. The module is IP20 rated, DIN-rail mounted via the ST Base Module, and compatible with base modules ST1B-S3Y2 and ST1B-E3Y2. It draws about 90 mA at 5 VDC and weighs 0.03 kg. Typical applications include packaging equipment, material handling systems, machine tools, production machinery, and process automation where compact remote digital output capability is required within industrial distributed I/O environments. Common replacements include ST1Y2-TPE3, ST1Y16-TE2, and ST1Y2-R2.
