KFD2-EB2.R4A.B REDUNDANT POWER SUPPLY FEED MODULE

Product parameters

Power supply: Rated voltage 20... 30 V DC (via terminal or Power Rail), power dissipation ≤ 1.3W, maximum power consumption ≤ 1.5W, rated current ≤ 4A, ripple ≤ 10%.

Input: Connect terminals 11+ and 12-, input voltage 20... For a 30V DC, two KFD2-EB2.R4A.B redundant configurations are required.

Output: Power Rail outputs 24 V DC, with A maximum of 4 A; Relay contact output (terminals 7, 8, 9), switch capacity 253 V AC / 2A or 40 V DC / 4A, mechanical life 10^7 times, electrical life 10^5 times.

Performance indicators: Supports RS-485 connection (terminals 13 and 15, terminal 14 is only used for testing), response time < 10ms, and fault signals are output through relays.

Isolation and Safety: The input/output is functionally isolated (50 V AC), which does not affect the functional safety (SIL) calculation. The protection class is IP20, and the electromagnetic compatibility complies with EN 61326-1:2013.

Certifications: CE, ATEX (II 3G Ex nA IIC T4 Gc), IECEx, cULus, in compliance with directives such as EN 60079-0.

Mechanical parameters: Dimensions 20 x 119 x 115 mm, weight approximately 100 g, installed on 35 mm DIN rail (EN 60715), screw terminal connection, ambient temperature -20... 60 °C.

Function

Provide A stable Power supply of 24 V DC with a maximum of 4 A for Power Rail, and support redundant configuration to ensure uninterrupted power supply.

It is equipped with replaceable fuses to protect the circuit from overload or short circuit.

It provides relay contact output (configurable as normally open or normally closed) for collective error message transmission to the controller.

It is equipped with a built-in green LED (power status) and a red LED (fault status), facilitating on-site monitoring.

Supports RS-485 connection (such as in conjunction with KFD2-WAC2-Ex1.D), compatible with all Power Rail versions, and provides group fuse functionality.

Application scenarios

KFD2-EB2.R4A.B is widely used in process automation in industries such as petrochemicals, pharmaceuticals, and oil refining, and is particularly suitable for hazardous areas that require highly reliable power supplies (such as Zone 2 or Div.2). It provides redundant power for the K-System isolation barrier, ensuring the stable operation of signal isolation modules such as transmitter power supplies or switching amplifiers. The equipment monitors faults through relay output and is suitable for process control, factory automation and machine automation scenarios, meeting the requirements of ATEX, IECEx and cULus certifications.
