The I/O modules are used for signal transfer and signal matching between the plant and the central modules. The input and output circuits are always fed into the I/O modules via cable plugs on the front side. The status of the digital output signals is shown on the LEDs of the cable plugs. The power supply is either via the cable plugs or via the I/O bus board. The order of the different I/O module types does not matter.
Carbomer
1.Carbomer (carbomer) is a high molecular weight polymer of acrylic acid bonded with pentaerythritol allyl ether or allyl sucrose. Calculated according to the dry product, the carboxylic acid group (-COOH) should be 56Chemicalbook.0%ï½?68.0%. Carbomer is a very important rheology modifier. The glue combined with water is acidic. The neutralized carbomer is an excellent gel matrix, which is important for thickening and suspension.
2.Carbomer (Carbomer) is a pentaerythritol and other resin that is linked with deformation. It is a very important and fantastic
rheological modulated chemistry book section. The neutralized carbomer is an excellent spring limit. , There are important
processes such as thickening and suspension, simple, good stability, and a wide range of deep, cream, and medium processes

Application:
Carbomer is used for topical formulations and suitable for preparation of gels, creams and coupling agent. Carbomer and
cross-linked acrylic resin as well as series products of these cross-linked polyacrylic acid are widely used at present and are often used in topical lotion, cream and gel. In a neutral environment, Carbomer system is an excellent gel matrix with crystal appearance and nice sense of touch, so Carbomer is suitable for preparation of cream or gel..
The ABB Drive FENA-11 CI871 hardware library (ABBDrvFenaCI871HwLib) contains hardware types to be used when configuring ABB Drive FENA-11, using PROFINET IO (CI871). FOUNDATION Fieldbus HSE The FOUNDATION Fieldbus HSE hardware library (CI860FFHSEHWLib) contains the communication interface for the FOUNDATION Fieldbus HSE link (CI860)
The controls can be adapted to the requirements of the plant by equipping them with the appropriate central modules. The following structures are possible with the H41q resp
In case the 5 V DC system power fails hardware clock and sRAM on the central module are buffered by a lithium battery which is also on the central module.
In case of an error the plant is to be driven in the safe state. For systems with a defined safety state this is the lowest energetic state.
The controller is equipped with 2 independent counters with inputs that can be configured for 5 V or 24 V voltage level. The required voltage level is determined by the user program with the Counter[0x].5/24V Mode system parameter.
Input A is the counter input, B is the count direction input and input Z (zero track) is used to reset. Alternatively, all inputs are 3-bit Gray code inputs (in decoder operation) The following modes of operation can be implemented:
Counter function 1 (depending on the count direction input signal)
Counter function 2 (not depending on the count direction input signal)
Decoder operation with attached absolute rotary transducer
The I/O modules are used for signal transfer and signal matching between the plant and the central modules. The input and output circuits are always fed into the I/O modules via cable plugs on the front side. The status of the digital output signals is shown on the LEDs of the cable plugs. The power supply is either via the cable plugs or via the I/O bus board. The order of the different I/O module types does not matter.
The positive pole is usable also for power voltage and control voltage. To achieve the valid values for the connection of single phase mains supplies, power supply units with bridge rectification and smoothing are required or stabilized power supply units.
The 5 V DC power is needed by the CPU, the control of the interfaces, and the I/O modules. It is generated by a clocked 24 V DC/ 5V DC power supply module bearing the F 7130A identification. The subrack is equipped with two power supply modules.
The power supply modules are paralleled. If one of them fails, the other supplies the PES.The 5 V DC output voltage of the power supply modules (for the CPU, I/O, and the interfaces) are monitored on the central unit checking undervoltage and failure.
The HIMA PES are installed in subracks 19 inch 5 resp. 4 units high. The H41q system family is a compact system consisting of a subrack holding all components such as central unit, power supplies, fusings, and power distribution, as well as input/output modules.
