SM321, Digital Input Module, AC 300 321-1FH00
Description The Siemens 6ES7 321-1FH00-0AA0 can be replaced by this item.SM321 with DI 16*DC 24V 120/230V AC All our Softlink 300 series digital input modules convert external power-level signals from processes into internal signals for programmable logic controllers. All the modules are compatible with Siemens S7-300 and VIPA 300V series, suitable for inputs from switches etc. The input modules provide galvanic isolation from CPU (of S7-300 or VIPA300V), and have LED indicators for every input channel.
