Applications
- Digital signal acquisition: The 4 digital inputs acquire DC signals with signal "0" and signal "1" ranges.
- Encoder and sensor connection: The module connects 2-wire sensors with a permissible quiescent current of up to 1.5 mA.
- Input diagnostics: The module provides diagnostics, short-circuit detection to ground, group error SF indication, and per-channel digital input status indication.
Key Features
- 4 digital inputs: The module has 4 digital inputs with a 24 V DC rated input voltage and IEC 61131 type 1 input characteristic curve.
- Input signal ranges: Signal "0" is -30 to +5 V; signal "1" is +11 to +30V. Typical input current for signal "1" is 8 mA.
- Parameterizable input timing: For standard inputs, timing is parameterizable at 0.1 / 0.5 / 3 / 15 ms.
- Encoder diagnostics: The module supports 2-wire sensors, diagnostics, short-circuit detection to ground by module, and group error SF and digital input status LEDs.
- 24 V supply and protection: The rated supply voltage is 24 V from the power module. Reverse polarity protection is provided, and encoder output voltage has electronic short-circuit protection.
- Isolation and cable length: Digital inputs are isolated from the backplane bus but not between channels. Maximum cable length is 1 000 m shielded or 600 m unshielded.
