Features Model

3 device versions with different power supply and control voltages.
Integrated power supply either as wide-range AC or DC power supply (85 to 264 V AC or 24 V DC)
Integrated 24 V encoder/load current supply:
For direct connection of sensors and encoders. With 300 mA output current also for use as load power supply.
6 integrated digital inputs 24 V DC (current sinking/current sourcing (IEC type 1 current sinking)).
4 integrated digital outputs, either 24 V DC or relay.
2 integrated analog inputs 0 to 10 V.
2 pulse outputs (PTO) with a frequency of up to 100 kHz.
Pulse-width modulated outputs (PWM) with a frequency of up to 100 kHz.
Integrated Ethernet interface (TCP/IP native, ISO-on-TCP)
3 fast counters (100 kHz), with parameterizable enable and reset inputs, can be used simultaneously as up and down counters with separate inputs or for connecting incremental encoders.
Expansion by additional communication interfaces, e.g. RS485 or RS232
Expansion by analog or digital signals directly on the CPU via signal board (with retention of CPU mounting dimensions)
Optional memory expansion (SIMATIC Memory Card)
PID controller with auto-tuning functionality
Integral real-time clock
Interrupt inputs: For extremely fast response to rising or falling edges of process signals.
Removable terminals on all modules
Simulator (optional): For simulating the integrated inputs and for testing the user program.
