Product Description
Key Features
- Counter module identity: TM Count 2x24V with 2 channels for 24 V incremental encoder or pulse generator signals.
- Digital I/O configuration: 6 parameterizable digital inputs and 4 parameterizable transistor digital outputs, with 3 inputs and 2 outputs per channel.
- Counting performance: Counting frequency up to 800 kHz with quadruple evaluation; input frequency up to 200 kHz.
- Supply and protection: 24 V DC rated load voltage with a permissible range of 19.2 V to 28.8 V, reverse polarity protection, and short-circuit-protected encoder supply.
- Installation and environment: S7-1500 mounting rail installation; operating ambient temperature is -40 °C to 70 °C horizontally and -40 °C to 40 °C vertically. Conformal coating is included.
Applications
- Incremental encoder counting: Counts signals from 24 V incremental encoders with A/B tracks, with or without a zero track.
- Pulse and frequency measurement: Measures frequency from 0.04 Hz to 800 kHz and cycle duration from 1.25 μs to 25 s.
- Configurable counter control: Supports hardware and software gates, event-controlled stopping, synchronization via digital input, and parameterizable counting ranges.
