< Terminals with test points
< Up to SIL 2 acc. to IEC 61508
This isolated barrier is used for intrinsic safety applications. The device supplies 2-wire SMART transmitters in a hazardous area. It transfers the analog input signal to the safe area as an isolated current value. Digital signals may be superimposed on the input signal in the hazardous or safe area and are transferred bi-directionally. If the HART communication resistance in the loop is too low, the internal resistance of 250 Ω between terminals 8 and 9 can be used. Test sockets for the connection of HART communicators are integrated into the terminals of the device.
Signal type Analog input
The device supports the following SMART protocols:
• HART
• BRAIN
• Foxboro 
Input signal 0/4 ... 20 mA
Output signal 0/4 ... 20 mA (overload > 25 mA)

• Output EEx ia IIC
• 24 V DC nominal supply voltage
• Device installation permissible in zone 2
• Conversion of current/voltage or voltage/current
• Elevation/Suppression of the "life zero"
• Accuracy 0.1 %
• EMC acc. to NAMUR NE 21 KFD2-CD-Ex1.32
The KFD2-CD-Ex1.32 transmits an electrical unit signal from the safe area to the hazardous area. The conversion of a current signal into a voltage signal and vice versa is possible. Current input option A current limit circuit in series to terminal 9 protects the device from damage. The max. voltage drop at the input is DC 4 V, allowing for the connection of several KFD2-CD32-Ex1.32 repeaters due to the low voltage drop in order to maintain multiple galvanically isolated outputs (signal duplication). Voltage input option The signal is transmitted to terminals 9 and 10 across an amplifier and the DC/DC converter within the allowable voltage range. A voltage limiter circuit protects the amplifier from incorrect input switching and overvoltage, but will draw current through a 50 mA fuse during operation. The fuse can be changed only by the manufacturer. Current output option The open circuit voltage is DC 24 V within the allowable supply voltage range at terminals 1 and 2. The max. load that can be applied is 850 ???. Voltage output option At least 20 mA is available within the allowable supply voltage range at terminals 1 and 2 which means that with 10 V output voltage, a load of at least 500 ??? must be connected
Used to drive I/P converters and valve positioners. Table: input/output options, type For options enclosed in parantheses, the transfer range for a base type is only partially used, i. e. 4 mA ... 20 mA from the base type 0 mA ... 20 mA.

 Output 45 mA at 11.2 V DC
 Logic input, non-polarized
 Error message output  Line fault detection (LFD)
 Up to SIL2 acc. to IEC 61508
This isolated barrier is used for intrinsic safety applications. It supplies power to solenoids, LEDs, and audible alarms, located in a hazardous area. It is controlled via a logic signal. The input has two defined states: 1-Signal = 16 V DC  30 V DC, 0- Signal = 0 V DC 5 V DC. At full load, 11.2 V at 45 mA is available for the hazardous area application. If the field impedance is > 10 kfor lead breakage or < 50  for short circuits a line fault is detected. During an error condition, the fault indication output deenergizes. A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
Supplementary information EC-Type Examination Certificate, Statement of Conformity, Declaration of Conformity, Attestation of Conformity and instructions have to be observed where applicable. 
Power feed module KFD2-EB2 The power feed module is used to supply the devices with 24 V DC via the Power Rail. The fuse-protected power feed module can supply up to 100 individual devices depending on the power consumption of the devices. A galvanically isolated mechanical contact uses the Power Rail to transmit collective error messages. Power Rail UPR-03 The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium profile rail 35 mm x 15 mm. To make electrical contact, the devices are simply engaged. Profile Rail K-DUCT with Power Rail The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables. Due to this assembly no additional cable guides are necessary. Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
