Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Electrically, the inputs conform to IEC 61131-2 Type 1 characteristics, with a rated input voltage of 24 V DC. A valid "1" signal is recognized at voltages between 13 V and 30 V DC, while a "0" signal is defined from –30 V to +5 V DC. This wide threshold band accommodates voltage drops along long cable runs and ensures reliable detection even with marginal sensor outputs. The typical input current of 7 mA at "1" signal is compatible with standard PLC inputs and does not overload typical sensor output stages.
