Product information
Overview
Applications
- Controlled positioning: The CPU supports controlled positioning.
- PID control: The CPU supports PID controller functions.
Key Features
- Compact CPU configuration: CPU 1214C with DC/DC/relay configuration, 75 kbyte integrated work memory, 4 Mbyte integrated load memory, and maintenance-free backup.
- Integrated digital I/O: 14 integrated digital inputs, including 6 inputs usable for HSC functions, and 10 relay outputs.
- Analog input capacity: 2 analog inputs for 0 to +10 V signals, with 10 bit resolution and 625 μs conversion time per channel.
- PROFINET communication: 1 isolated PROFINET interface with RJ 45 connection, automatic transmission-rate detection, autonegotiation, and autocrossing.
- Supply and protection: 24 V DC supply with a permissible range of 20.4 V to 28.8 V; IP20 degree of protection. Relay outputs have no internal short-circuit protection, which must be provided externally.
