F3237 984323702 8 Channel Safety-Related Input Module HIMA

The module contains a redundant, safety-related processor system. Because of this, all thetests are executed directly on the module.The main test routines are:
-Linearity of the A/D converters
– Overflow of the A/D converters
– Cross talking between the eight input channels- Function of the input filters
-Function of the lO bus communication

　　Notes to the safety-related operation and use

Screened cables have to be used for the field input circuits, twisted cables are recommended.lf it is sure that the environment of the transmitter up to the module is free from interferencesand the distance is relatively short (e. g. inside a cabinet) then the cabling can be performedwithout screened cables or twisted cables. However, the interference immunity of the analoginputs can only be achieved by using screened cables.

Planning notes for ELOP ” For each input channel of the module exists an analog input value and an appertaining channelfault bit. With activated channel fault bit a safety-related reaction has to be programmed inELOP ll related to the corresponding analog input.

Recommendations for the use of the module according to lEC 61508,sIL 3- Cables for power supply shall be locally separated from the input circuits,- Application of a suitable earthing must be regarded,

– Measures against rising of the temperature have to be taken outside of the module, e. g.fans in the cabinet,

– Recording events in a logbook for operation and maintenance.

A maintenance of the module is not required. In case of fault there is a switch-off. The failedmodule must be replaced.

Z7128 Cable plug with transmitter supply

For the supply of transmitters the Z7128 cable plug with transmitter supply is available (suita-ble only for two-wire connections).
