Product Description
Key Features
- Exact module identity: Product type designation: TM Count 2x24V; 6ES7550-1AA01-0AB0.
- Encoder channels: 2 channels for 24 V incremental encoder or pulse encoder signals; input frequency up to 200 kHz and counting frequency up to 800 kHz with quadruple evaluation.
- Digital I/O: 6 digital inputs and 4 transistor digital outputs, with 3 inputs and 2 outputs per channel.
- Supply and mounting: Rated load voltage: 24 V DC; permissible range: 19.2 V to 28.8 V DC. Rail mounting on an S7-1500 mounting rail.
- Firmware and engineering: Firmware version V2.0; FW update possible. STEP 7 TIA Portal configurable/integrated from V16 with HSP 0332 / V17.
- Protection and diagnostics: Reverse polarity and short-circuit protection, with diagnostic alarm, hardware interrupt, wire-break and short-circuit diagnoses.
Applications
- Incremental encoder counting: Supports incremental encoders with A/B tracks, 90° phase offset, including zero track.
- Pulse encoder counting: Supports pulse encoders, including pulse encoders with direction and with one impulse signal per count direction.
- Frequency and cycle-duration measurement: Provides frequency measurement from 0.04 Hz to 800 kHz and cycle-duration measurement from 1.25 μs to 25 s.
