Product information
Overview
Applications
- Frequency measurement: The source specifies frequency measurement as a supported counter function, with counting frequency up to 100 kHz.
- Controlled positioning: The source specifies controlled positioning as a supported counter function.
- PID control: The source specifies a PID controller as a supported counter function.
Key Features
- Integrated digital I/O: 8 digital inputs and 6 relay outputs are integrated; relay output switching capacity is 2 A with resistive load, maximum.
- Analog input capacity: 2 analog inputs support 0 to +10 V; resolution with overrange is 10 bit maximum and conversion time is 625 μs per channel.
- PROFINET interface: 1 isolated PROFINET interface with RJ 45 (Ethernet), automatic transmission-rate detection, autonegotiation and autocrossing.
- Supply and memory: Power supply is DC 20.4-28.8V DC; integrated work memory is 50 kbyte and load memory is 1 Mbyte.
- Programming package: Engineering uses STEP 7 V11 SP2 or higher.
- Protection and diagnostics: The CPU has IP20 protection, a diagnostic buffer, forcing, and status/control for inputs/outputs, memory bits, DBs, distributed I/Os, timers and counters.
