Product information
Overview
Applications
- Counter input operation: Up to 2 digital inputs can be used as counters with a maximum counting frequency of 6 kHz under FS04 and firmware V2.2.1 or higher.
- Gate start/stop control: Parameterizable digital input functions include gate start/stop.
Key Features
- 32 digital inputs: Provides 32 parameterizable digital inputs with 24 V DC rated input voltage.
- Counter capability: Up to 2 inputs can be used as counters with a maximum counting frequency of 6 kHz under FS04 and firmware V2.2.1 or higher; counting width is 32 bit.
- Configurable input delay: Standard input delay is parameterizable from 0.05 ms to 20 ms.
- Diagnostics and interrupts: Provides diagnostics, diagnostic alarms, hardware interrupts, supply-voltage monitoring and wire-break diagnosis to I < 350 μA.
- Flexible connection options: The front connector uses screw terminals or push-in terminals and must be ordered separately.
- SIMATIC engineering support: STEP 7 TIA Portal is configurable/integrated from V13 SP1, and STEP 7 is configurable/integrated from V5.5 SP3.
