RCB 200N1 : Transient Immunity Test Generator meeting FORD EMC-CS-2009.1

Highlights

Approved by Ford acc. to EMC-CS-2009.1 requirements

Pulses CI 220: A1, A2-1, A2-2, C-1 and C-2

Pulse CI 260: F

Pulses RI 130: A2-1, A2-2 using a coupling test fixture

Fixed repetition times and pseudo-random timing

Automatic control of mode and switch settings by micro-controller

Easy control by manual operation

EOL status control of the relay as per FORD requirement

Internal/external trigger mode operation

Application

RCB 200N1 - Generation of relay switching transients

As per FORD EMC-CS-2009.1 a part of the test pulses is not generated using a transient pulse generator similar to the ones defined as per ISO 7637 but being based on a circuitry including a Potter & Brumfield 12VAC relay and specifically defined components such as inductors, capacitors, resistors and switches with the aim of simulating "real-world transients".
The EM TEST RCB 200N1 transient generator meets the requirements set out by the FORD EMC-CS-2009.1 standard document. It is built using the components outlined in Figure F-1 to generate pulses such as CI 220 A1, A2-1, A2-2, C-1 and C-2, CI 260 F and RI 130 A2-1 and A2-2 for which the RCB 200N1 is built into a metal housing. For RI 130 testing the RCB 200N1 offers BNC-type coaxial outputs to connect the specified test fixture needed for this particular test.

Benefits

Micro-processor controlled RCB 200N1 ensures easy operation

While including 8 different pulses and three different modes to sequence these pulses the operation is as easy it can be. A micro-controller sets the switches based on the selected ID (CI 220, CI 260 and RI 130), pulse (CI 220: A1, A2-1, A2-2, C-1 and C-2, CI 260: F or RI 130: A2-1 and A2-2) and mode (M1, M2 and M3) of application. LEDs are indicating the selected pulse and test mode as well as the status of the relays (SW0 to SW4) as requested by the standard.
The test modes Mode 2 and Mode 3 are defined based on a pseudo-random timing sequence for the application of the pulses. This is automatically done by the built-in micro-controller. Tests can be run in sequences or endlessly.
The Potter&Brumfield relay is required to be replaced after using it for approx. 100hours testing due to degradation of the performance. A built-in counter is active in the background counting the operation time of the relay. The EOL LED indicates the current EOL status.
To meet the requirements for RI 130 testing the RCB 200N1 is built into a metal box with the relay inside still easily accessible for replacement.
To trigger the pulses the unit has means to connect an external trigger source while it will automatically be triggered internally when no external trigger source is connected.

Design of the RCB 200N1

RCB 200N1 - strictly designed as per EMC-CS-2009.1

Ford strictly specifies the circuitry and components to be used for a compliant transient generator. The design of EM TESTs RCB 200N1 strictly respects these requirements.
