Siemens S7-200 CPU 226 AC/DC/Relay
The Siemens S7-200 CPU 226 AC/DC/Relay
This PLC unit features 24 digital inputs (24V DC) and 16 relay outputs rated for 2A at 230V AC or 30V DC.
The CPU contains 10KB of program memory and 10KB of data memory, with a fast instruction execution
speed of 0.22 microseconds per operation.For high-speed applications, the CPU includes six high-speed
counters supporting frequencies up to 30kHz and two PWM outputs with 20kHz maximum frequency.
Communication is handled through two independent RS485 ports supporting PPI and MPI protocols, while
expansion capability allows for connection of up to seven additional modules.The unit operates on 120/230V AC power
(85-264V AC range) and measures 196 × 80 × 62 mm, weighing 660 grams. Key features include a built-in real-time clock
with battery backup, PID control functionality, and 50-day program retention during power loss.Programming requires
STEP 7-Micro/WIN software and a PC/PPI cable for RS485 connection.
