Beckhoff's KL29xx (TwinSAFE Safety Output) series only officially releases the KL2904 (4-channel 24V DC, 0.5A, Cat.4/PL e/SIL3); there are no datasheets, order numbers, or CE/UL certifications for the KL2908 (8-channel Safety Output); "KL2908" on the market is mostly a typo for KL2808 (standard 8-channel output) or KL2904, a non-original modification, or a counterfeit.
Beckhoff special terminals will have a 4-digit extension number added to the standard model (e.g., KLxxx-00xx); there is no independent KL2908 basic model.
