6ES5465-4UA12 - Analog Input Module - SIEMENS - SEI

The analog input modules convert the analog signals from the process into digital values, which can be processed by the programmable controller.

Application of analog input modules:
- Process monitoring
- Measuring physical quantities, e.g. in mechanical en gineering, process engineering, building services automation
- Control engineering

Analog input modules with 16, 8 and 4 inputs are available. The modules require one slot.

Front connectors are used for terminating the signal cables. Modules and front connectors may be inserted and removed under power (except for the 466 input module).

Adhesive labels are supplied to identify modules and front connectors.

460 input module:
- Eight floating channels
- Sequential measured value acquisition by means of op tovoltaic multiplexer
- Measuring range selection by means of measuring range modules
- Direct acquisition of thermo couple voltages
- Direct four wire connection of resistance type sensors, e.g. Pt 100
- Power supply from L+, L S Use in large plants/machines with high common mode voltages
- For closed loop control applications with time constant ranging from seconds to infinity.

463 input module:
- Four individually isolated channels
- Simultaneous scanning of all channels within 162/3 or 20ms(50or60Hz)
- Measuring range selection via jumpers in the front connector
- Acquisition of transducer signals
- For fast, noise immune measured value acquisition even under unfavourable potential conditions
- For closed loop control ap plications where speed is a critical factor (time constants >20 ms)

465 input module:
- 16 non floating channels
- Sequential measured value acquisition with semiconductor multiplexers
- Measuring range selection by means of measuring range modules
- Direct acquisition of thermo couple voltages
- Direct four wire connection of resistance type sensors, e.g. Pt 100
- Use in small scale plants/machines where potential conditions are not a critical factor.

Common features of the 460, 463 and 465 input modules: 
- Integrating analog digital conversion with a high de gree of noise suppression at 50 (60) Hz and suppression of harmonics
- Enable input and input sig nals can be disabled
- The 460 4 input modules re quire two 498 measuring range modules
- The 465 4 input modules re quire two or four 498 mea suring range modules, depending on whether up to 8 inputs or more than 8 inputs are used

466 input module:
- Eight differential or 16 individual channels (floating)
- Instantaneous value coding S Measuring range selection through fixed wiring at the front connector
- For closed loop control applications where speed is a critical factor (time constant >4 ms).
