Description
The Siemens SIMATIC S7-300 SM 335 is designed for high-speed acquisition and output of analog signals in demanding automation applications. Its 4 analog inputs support voltage and current signals, including ±1 V, ±10 V, ±2.5 V, 0–2 V, 0–10 V, ±10 mA, 0–20 mA, and 4–20 mA, while up to two input channels can be configured for current measurement. The analog inputs provide up to 14-bit resolution, and the module includes a 10 V / 25 mA encoder supply.
The four analog outputs provide ±10 V or 0–10 V signals with up to 11-bit plus sign / 12-bit resolution and fast conversion times. In addition to its analog I/O channels, the SM 335 includes one interval counter input capable of measuring pulse intervals with 0.5 μs resolution and frequencies up to 400 Hz. The module also supports programmable end-of-cycle and diagnostic interrupts, group-fault indication, and electrical isolation from the S7-300 backplane bus.
