SIPLUS S7-1200, сигнальная плата дискретных входов SB 1221 4DI, рабочая температура -25 ... +55°C,со стойким покрытием, на основе 6ES7221-3BD30-0XB0 . Дискретные входы 4 DI, =24 В, 200 кГц SIMATIC S7-1200 Basic Controller - Flexible thanks to wide variety of communication options If you only have to extend your SIMATIC S7-1200 CPU with a few inputs or outputs, signal boards are a good alternative to signal modules. Signal boards are plugged directly onto the front of the controller (also possible with the CPU 1211C) and are available as digital and analog input, output and hybrid modules. A communications board with an RS 485 interface is also available. Signal boards thus permit subsequent expansion of the configuration without requiring any further space in the control cabinet. Just like the CPU, the digital input and output modules are also protected against extreme ambient conditions. Due to the 100% conformal coating they can withstand biologically, chemically and physically active substances, condensation, frost, and corrosive gases. Regardless of the conditions, your digital signals are reliably recorded.
