INSTRINSIC SAFETY BARRIER

Series 9260 Ex i transmitter supply units can be used for the intrinsically safe operation of transmitters or intrinsically safe mA sources such as 4- wire transmitters. The device allows HART signals to be transmitted in both directions. The portfolio includes one- and two- channel devices and a variant for signal duplication.
Universal use for transmitters and mA sources (4- wire transmitter)Slim design  12.5 mm wide for one- and two- channel versionsCan be used for functional safety levels up to SIL 2 (IEC/ EN 61508)

1-channel isolated barrier
• 24 V DC supply (loop powered)
• Current limit 45 mA at 10 V DC
• Up to SIL 3 acc. to IEC 61508 This isolated barrier is used for intrinsic safety applications. The device supplies power to solenoids, LEDs and audible alarms located in a hazardous area. The device is loop powered, so the available energy at the output is received from the input signal. The output signal has a resistive characteristic. As a result the output voltage and current are dependent on the load and the input voltage At full load, 10 V at 45 mA is available for the hazardous area application

1-channel isolated barrier
 24 V DC supply (Power Rail)
 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.

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!
