Product information
Overview
Applications
- Pulse and encoder counting: Supports continuous counting, event-controlled stop, hardware or software gates, synchronization via digital input, and incremental acquisition.
- Frequency measurement: Performs parameterizable frequency measurement from 0.04 Hz to 800 kHz with 100 ppm accuracy, depending on measuring interval and signal evaluation.
- Cycle duration measurement: Performs parameterizable cycle duration measurement from 1.25 μs to 25 s with 100 ppm accuracy, depending on measuring interval and signal evaluation.
- Velocity measurement: Supports velocity measurement with 100 ppm accuracy, depending on measuring interval and signal evaluation.
Key Features
- 2-channel counter module: TM Count 2x24V provides 2 channels for 24 V incremental encoders or pulse encoders, with 2 counters and fast mode.
- High-speed counting: Counting frequency reaches 800 kHz with quadruple evaluation; input frequency is up to 200 kHz.
- Digital I/O capacity: The module has 6 parameterizable digital inputs, 3 per channel, and 4 parameterizable transistor digital outputs, 2 per channel.
- 24 V supply and protection: Rated load voltage is 24 V DC with a permissible range of 19.2 V to 28.8 V, reverse polarity protection, and short-circuit-protected encoder supply.
- Measurement functions: Parameterizable frequency measurement covers 0.04 Hz to 800 kHz, while cycle duration measurement covers 1.25 μs to 25 s.
- Mounting and diagnostics: The module mounts on an S7-1500 mounting rail and provides diagnostic alarms, hardware interrupts, wire-break and short-circuit monitoring, plus RUN, ERROR, MAINT, PWR and channel-status LEDs.
