Product Details:
Manufacturer : Pepperl+Fuchs
Product No. : KFD2-HMM-16
Product Type : HART Multiplexer Master

Features:

• 16-channel
• 24 V DC supply (Power Rail)
• HART field device input (revision 5 to 7)
• Up to 15 KFD0-HMS-16 slave units can be connected
• Up to SIL 3 acc. to IEC/EN 61508

Function

This HART Multiplexer Master operates up to 256 analog field instruments. The built-in slave unit in the HART master operates the first 16 field instruments. If more than 16 field instruments are required, up to 15 additional HART Multiplexer Slaves KFD0-HMS-16 can be connected.

The slave units are connected to the master with a 14-pin flat cable. The connector for the ribbon cable is found on the same housing side as the connectors for the interface and the power supply.

The analog signals are separately linked to a termination board via a 26-pin flat cable for each unit. Sixteen leads are reserved for the HART signal of the analog measurement circuits. The remaining 10 leads are sent to ground.

This unit is designed with removable terminals and can be connected to the Power Rail.
