RCB 200N1 - generator of relay switching transients
As per FORD EMC-CS-2009.1, part of the waveforms are not ableto generated by using a transient pulse generator which applied ISO 7637 while being based on a circuit 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".
EMTEST RCB 200N1 meets the requirements of FORD EMC-CS-2009.1 standard. It is built using the components outlined in FORD EMC-CS-2009.1Figure 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, RCB 200N1 offers BNC-type coaxial outputs to connect the specified test fixture needed for this particular test.
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
BenefitsMicro-processor controlled RCB 200N1 ensures easy operation
While including 8 different waveform test and three different test modes, 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 mode 2 and mode 3 are defined based on a random timingfor the application of the waveform tests. This is automatically done by the built-in micro-controller. Tests can be run in sequence or continuously.
The Potter&Brumfield relay is required to be replaced after using for approx. 100hours testing. A built-in counter is active for counting the operation time of the relay. The EOL LED indicates the current EOL status.
To meet the requirements for RI 130 testing, RCB 200N1 is built into a metal box with the relay inside still easily accessible for replacement.
To trigger the waveforms, the unit has means to connect an external trigger source while it will automatically be triggered internally when no external trigger source is connected.
