siemens s7-300
compatible i/o module |
| |
SM 321 compatible with S7-300v |
| |
|
Compatible with S7-300 and VIPA 300V system.
The
digital inputs convert the external binary signals from the process into
the internal signal level of the programmable controller(S7-300 and VIPA
300V). The input modules are suitable for connection of 2-wire proximity
switches. Have protection of polarity reverse, can install safely. |

SM 322 compatible with S7-300 |
|
|
|
Compatible with S7-300 and VIPA 300V system.
The
digital outputs convert the internal signal level to the external signal
level required for the process. The output modules are also suitable for
connection of ,for example ,solenoid Valves , contactors ,and small-power
motors within the permissible data. With LED diagnose (Green LEDs indicate
the signal states for the outputs.)

Bus connector for Profibus |
|
|
The
bus connectors are used to connect a PROFIBUS station to the PROFIBUS
cable. The connector is quickly mounted and has integrated, connectable
terminating resistors. we offers the bus connector with a vertical and 35°outgoing
cable, and for transmission rates up to 12 Mbaud.
The
bus connector is plugged directly onto the PROFIBUS interface (SUB-D
connector, 9-way) of the PROFIBUS stations. The PROFIBUS cables are
connected using 4-way screw terminals. |

Front Connectors for
s7-300 |
|
|
|
The 20-way and
40-way front connector permits simple connection of siemens
S7-300 sensors and actuators to input/output modules of or other
manufacturers . The wiring can thus be retained even in the event of
module replacement.
