6ES7138-6AA01-0BA0 ET 200SP TM Count 1x24V Counter Module 3DI/2DQ | Siemens

The Original New Siemens 6ES7138-6AA01-0BA0 SIMATIC ET 200SP TM Count 1x24V is a high-speed technology module for counting and position detection in distributed I/O systems. It features one 24V counter channel supporting incremental encoders or pulse encoders, plus three additional digital inputs and two transistor outputs for integrated control tasks. Designed for applications requiring precise counting, frequency measurement, and position feedback in compact automation systems.

Core Engineering Highlights:
1x 24V counter channel for incremental/pulse encoders | 200 kHz max input frequency | 800 kHz max counting frequency with quadruple evaluation | 3x additional DI (24V DC, Type 3) | 2x transistor outputs (0.5A per channel) | 24V encoder supply (300 mA, short-circuit protected) | 1W typical power loss | Firmware V2.0 | Firmware upgradeable | Isochronous mode support | I&M0 to I&M3 data | BU type A0 compatible | Colour code CC00 | IP20 protection | –30°C to +60°C operating (horizontal)
