Applications
- Incremental counting: Counts signals from 24 V incremental encoders, including A/B tracks with 90° phase offset and zero track.
- Pulse counting: Counts pulse encoder signals, including pulse encoders with direction and with one impulse signal per count direction.
- Frequency and cycle-duration measurement: Performs frequency measurements from 0.04 Hz to 800 kHz and cycle-duration measurements from 1.25 μs to 25 s.
- Position detection: Provides incremental acquisition for position detection.
Key Features
- 2-channel counter module: TM Count 2x24V has 2 channels for 24 V incremental encoders or pulse encoders, with 2 counters and counting frequency up to 800 kHz with quadruple evaluation.
- Digital I/O per channel: Each channel has 3 parameterizable digital inputs and 2 parameterizable transistor outputs.
- Encoder signal support: Supports incremental encoder A/B tracks with 90° phase offset, A/B tracks with zero track, pulse encoder, and pulse encoder with direction.
- 24 V supply: Rated load voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V and reverse polarity protection.
- Diagnostics and isolation: Provides diagnostic alarm, hardware interrupt, wire-break, short-circuit, supply-voltage, and A/B transition-error diagnostics. Channels are isolated from the backplane bus.
- Mounting and dimensions: Rail mounting uses an S7-1500 mounting rail. Dimensions are 35 mm wide, 147 mm high, and 129 mm deep; weight is approximately 250 g.
